Eldrane Higlight Reel Ardenvale Tactician - CUBEABLE- Rate body and ability. But the extra Adventure makes this a flexible, and split payment, card. Everything is rate, but having flexible in any archetype is invaluable.
Crashijg Drawbridge - BORDERLINE- Surprisingly rare ability, especially as it can go in any color. Sad the ability to tap for haste, takes out a defender from the turn.
Crystal Slippper - CUBEABLE- Cheaper than other Pauper options, and still gives a stat boost for little mana invested.
Dawrven Mine (all ELD land type nonbasics) - BORDERLINE- harder to trigger in non-mono lists and those are usually rarer. If your cube supports Mono more than most, W/B/U are very good and the others are passable. Even better with ways to reuse.
Faerie Guidemother- BORDERLINE- Surprisingly useable. While it is underwhelming on paper, there is a value to the flexibility of being playable on any given turn in one way or the other. Finding a spot is harder as this doesn't fit as universally as the Tactician
Fierce Witchstalker - CUBEABLE- While 4cmc simone of the highest contested spots, this has trample AND gives a 3 life kickback. It really can go in any Green deck as this body is always good.
Forbidding Fruit - BORDERLINE- Black Divinations co e I. A variety, this giving 3 life back (or generating an artifact) is suitable in certain cubes.
Giant's Skewer - BAD - The costs are just too high. Needing colored mana to cast, 3 to equip, and then only getting the Food when the body is in combat... AND that life needs mana to be activated! Too much for a perfect storm of events to happen.
Gingerbrute - BORDERLINE- Semi-evasive, cheap, and any color. If you like Aggro, and/or run heavy equipment, this should be included. The Food ability is what seals the deal for pro-Aggro usage.
Rimrock Knight -BORDERLINE- It is flexible, and "cannot block" isn't a dealbreaker. But everything combines to just be par for 1R Red aggro bodies. The Adventure portion is going to be why you run it over its competitors if you do.
Silverflame Ritual - BORDERLINE- If WWW is realistic in your cube, this is a decent finisher. If not. We have other options.
So Tiny -Borderline- While the front portion of -2/-0 is not as impressive, having Flash and being able to grom to -6/-0 for only U is actual a rather impressive aggro/tempo card. Depending on setup, Flash Enchantment has its uses too.
Trapped in the Tower - CUBEABLE- 2 mana Arrest that cannot hit Flying, kinda a fair trade for costing 1 less. Most Flying creatures do not have activated abilities worth using.
Weapon Rack - BORDERLINE- Yes it activates at Sorcery speed. But being able to spread out 3 counters in any color may have uses depending on your other options. It is not unplayable, but it is likely not a top tier include either.
Wicked Guardian - BORDERLINE- 4cmc 4/2 that draws a card is better than average fodder. And depending on when it is played, it may not even cost you a Creature. It may only cost a useless token. The bigger problem is the take-down proclivity.
Wildwood Tracker - BORDERLINE- Very aggressive for Pauper. And most Green bodies are not humans. Main downside is it is an attack bonus.
Witching Well - BORDERLINE- Very playable. Depends on your Cube's needs. Smoothing draws, then eventually being an Inspiration is decent. Omen of the Seas seems more powerful in a vacuum.
Theros Beyond Death - Highlights (Cubeable/Borederline/Bad) Daybreak Chimera - Cubeable - The scaling price for a 3/3 Flier means this often will find a speedy arrival or cheap deploy. Only real negative is the WW in the cost, but that means it will not be a splash
Discordant Piper - Borderline - Strictly for the Sac-themed archetype. It is good there, but otherwise it is a 2/1 that makes a spare blocker
Arena Trickster - Bad (with room to improve - No evasion. Needs more stuff to play on opponent's turn, so it doesn't get better for likely 2 turns; play, their turn, back to you who keeps mana open, their next turn when you can play something.
Ilysian Caryatid - BORDERLINE- The jump in mana from 1->3 vs 2->4 has mana articles written. Being splashable, fixing and acceleration in a co,or known for fat bodies may make this a Midrange-exclusive, or slower Tempo. But it will allow greedy decks more options. Better in 4-5C supported cubes
Irreverent Revealers - BORDERLINE- The joke of calling them "irrelevant" will be said no less than twice per draft. However, this allows a flexible slot that is basically Sideboard (Pre-Board here) answer to equipment and the threatening Serrated Arrows. If not, it is a Goblin Chariot. Better in Average Cubes.
Lampad of Death's Vigil - Borderline - Not just for Sac-Archetype, this is on par with the Rusalka. Being an Enchantment Creature has it's own interactions to consider. Many of the stats and features (colorless activation, 1/3 for 1b) can be useful. It is not a heavy signal to play Sacrifice though.
Leonin of the Lost Pride - CUBEABLE- We have seen 3/1s before. But the incidental graveyard hate is becoming more relevant. Fighting Escape, Gravediggers, Dredge, etc may warrant this over most others in its class. Not the best of the 3/1s, but Top 3 likely.
Loathesome Chimera - BORDERLINE- Depending on your experiences with this card, it is either a Hidden Gem, or Average Fodder. Escapemis proving a useful ability in limited. And Green can be part of the GBU self-mill rather easily, or simply get more oomph late game for less cards
Mindwrack Harpy - BORDERLINE- Unique in that it works first turn, and every turn after as well as having an on-rate body. If this is for you, you already know.
Mire's Grasp - BORDERLINE- Best in Orzhov Control/Tempo with Heliod's Pilgrim and co. It is Last Gasp meets Dead Weight. Not much more to say. It fits your needs or it doesn't.
Mogi's Favor- BORDERLINE- Flexible and recurring. But likely it is just a ping spell. It can be everything from a very aggressive pseudo-equipment that sometimes kills tokens and weenies. Or it can be a black Flame Jab
Naiad of Hidden Coves -Borderline- This is an obvious combo for Capsize. But it also works with Flash, Retrace and Flashback Instznts. Combined with Familiars for redundancy, this can start to form a spell slinger archetype.
Omen of the Sea - CUBEABLE - It is very good for being a multitude card with Auramancer and Skyfisher effects. As-is it also give draw smoothing later when a mana-oppurtunity is available. Fits in any deck that splashes blue.
Pharika's Libation- BORDERLINE- Edicts are useful for keeping in check Hexproof and less Creature dense decks. Allowing black decks to also address Pesilence and Pacifism is useful for diversity in decks that normally need a 3rd color to do so; mostly B/R.
Relentless Pursuit - BORDERLINE- Saruration of the Green Dig->Graveyard. But for 3cmc getting mana and gas off the top is not the greatest, but a very welcomed addition to almost any green deck.
Satyrs Cunning - BAD - Slow, expensive, impactless. Even for Sacrifice type, this is an early cut.
Rumbling Sentry - BAD - So close to being acceptable. But JUST Scry 1 does not validate a very white midrange body
Sentinel's Eyes - CUBEABLE- Works great with Exert, but also with almost any body to turn it into a better threat. Vigilance can change threat evaluation for tight races. Low costs every way of casting makes this a great deal.
Skophos Warleader - BORDERLINE- Sac outlet that is also a threat. Menace on big bodies feels different from cheap smaller ones.
Thirst For Meaning - BORDERLINE- Every set will have this card's value reevaluated. It is an instant, but unlike Compulsive Research, it will almost always be discard 2. Many times the Enchantment in hand will be removal you want.
Underworld Charger - CUBEABLE- Aggro has an on-curve threat and late game threat. If this is not dealt with properly, it will always be a viable play that doesn't use another card.
Underworld Rage-hound - BORDERLINE- Being a 3/1 on first pass is less exciting in Red. But, always being able to field a 4/2 after its death/discard is a legitimate threat, if a slightly costly one. Always having gas is a problem for Red, and this addresses that.
Voracious Typhon - BORDERLINE- 4/4 for 4 is the standard, adding a flood/ramp mode is viable. Depends on the needs of an over-taced 4cmc Green Creature slot
Warbirar Blessing - BORDERLINE- Cartouche should be played first. If the appeal of an Aura with Fight needs a 2nd card, here it is. Otherwise it feels underwhelming, despite an appropriate cost.
Wings of Hubris - BORDERLINE- "Just Flying" is not always worth it. Sometimes it is; looks at Midrange decks. The sacrifice option giving the final blow makes this a tempting slot to include.
Witness of Tomorrows - BAD - All the other 5cmc 3/4 Fliers blue has that have ETBs are much more impactful. This would need 13 mana (!) to do what the other ETB Scry/Surveil 2 bodies do.
