I really like the idea of epic spells as either last ditch Hail Mary plays or as intricate well built machines to take most use of them. Out of the 5 the White one Enduring Ideal is easily the best of the bunch and I have made plenty of Commander decks to take advantage of that card. Eternal Dominion is a card I always wanted to put in a deck so it seems like a good big dumb excessive card on this pile of spells. Bonus Round on the other hand is a card which slots well into how I have enjoyed making decks in the past so building the best Bonus Round machine didn't seem that hard.
Yidris was chosen specifically because I wanted a deck that didn't have white and I didn't want to run Partners because I didn't want to take up the slot however I expect Thrasios & Vial Smasher would work plenty well (less Kydele because of the lack of artifacts). Also his cascade can play well with casting a bunch of spells in the deck.
Card Picks
Copy
Copy
1x Bonus Round - cast it once for fun, more than once who can say what happens
1x Dualcaster Mage - goes infinite, corpse dancable, sneak attack-able
1x Reiterate - goes infinite, repeatable
Tutor
1x Dark Petition - A tutor that most times will also be a ritual is a hell of a thing
1x Demonic Tutor - The gold standard
1x Entomb - with the amount of recursion this is gold
1x Intuition - So many ways in this deck to make terrible piles for opponents out of this card
1x Lim-Dul's Vault - Setting up is Fun
1x Mystical Tutor - Really good in a deck running as many spells as it is, not as good with Bonus Round sadly
1x Vampiric Tutor - See above
1x Spellseeker - Finds a high % of this deck and also is a creature so is exploitable in those ways creatures are
Ritual
1x Cabal Ritual - Either a Black Desperate Ritual or even better
1x Dark Ritual - the Gold Standard
1x Desperate Ritual - Making a lot of red is in the interest of this deck
1x Pyretic Ritual - See above
1x Seething Song - 3 for 5 is such a nice number
1x Inner Fire - Immense potential in this deck
1x Manamorphose - Rituals and Draw one of the most Potent Bonus Round cards
1x Rude Awakening - Can go infinite, Can in the right situations lead to the kill
1x Turnabout - Infinite Potential, also a wonderful card in slowing down opponents if needed
Ramp
1x Chromatic Lantern - 4 color deck needs this and it taps for mana unlike Prismatic Omen
1x Cultivate - this might get cut for basics in the deck
1x Farseek - real good ramp in 4c
1x Rampant Growth - see cultivate
1x Tempt with Discovery - people are often greedy fools
Draw
1x Ad Nauseam - A bit of spice never hurt anyone, much
1x Brainstorm - Gold Standard not good with Bonus Round
1x Cathartic Reunion - Draw and Yard filling never bad
1x Faithless Looting - see above
1x Tormenting Voice - see above
1x Frantic Search - The all time king of draw spells IMO especially paired with a Bonus Round
1x Mystic Remora - extremely potent first turn drop in the right crowd
1x Ponder - I prefer this one over the others for the shuffle
1x Sensei's Divining Top - I see this in some ways as more of a staple than Sol Ring
1x Sylvan Library - who needs a life total anyway
1x Wheel of Fortune - 3 mana 7 Cards
Recursion
1x Archaeomancer - creature recursion
1x Eternal Witness - see above
1x Corpse Dance - plays with the creatures in deck well, can also give Yidris haste to set up a big play if someone leaves an opening
1x Mizzix's Mastery - Ultimate spellslinger card, casts all the spells so bonus round becomes a wild time
1x Mystic Retrieval - spell recursion for things is potent with BR
1x Noxious Revival - see above
1x Past in Flames - if we are going to be filling a graveyard should have some recursion with flashback
1x Snapcaster Mage - never leave home without him
1x Yawgmoth's Will - when you just want to keep the storm going
Removal
1x Abrupt Decay - the most dangerous things in Commander I typically find are 3 mana or less this is one of the best ways to remove all of them
1x Chain of Vapor - people rarely take the offer on this card
1x Cyclonic Rift - this card has a reputation for a reason
1x Force of Will - not a big pact fan, will gladly give up a blue spell to stop a spell
1x Krosan Grip - nothing compares
1x Meltdown - new card testing out, see a lot of artifacts played near me
1x Nature's Claim - when you need that one mana silver bullet
1x Remand - Draws cards and more important can be used to reset cards to get more Bonus Round triggers
1x Snap - worst case is a free removal spell, once you add on some Rounds it turns into a ritual as well and can even start resetting our creatures too
Other
1x Eternal Dominion - Last Ditch Effort, with enough copies can overwhelm opponents with their own decks, doesn't work against every kind of deck (like this one for example)
1x Ghostly Flicker - Goes infinite, can become a ritual with some copies happening, most of creatures in deck can use a reset from time to time
1x Laboratory Maniac - This deck draws a lot of cards
1x The Locust God - See above
1x Life from the Loam - one of the most efficient ways to stay on land drops and fill a graveyard
1x Mindclaw Shaman - in the right match-ups this card can be a backbreaker, also real good at fishing for counterspells
1x Villainous Wealth - Cast a bunch of spells for free, potential to deck opponents too with enough mana
1x Scroll Rack - very few cards can replace your hand for a new one with this little investment, one of the few artifacts that make the cut
1x Shaman's Trance - meta call but as I have killed a table with Player A's Lotus Petal and Player B's Brainstorm before I love it
1x Sneak Attack - One red mana for an ETB of a creature on the list above is very good
1x Tendrils of Agony - Storm Finisher
1x Mind's Desire - The best balance between outrageous and amazing card in the entire game of Magic the Gathering, once you start adding everything else this deck does into this card the results can be wild.
Stuff I specifically stayed away from
Extra Turns, they could slot in very easily but I more want to build one massive turn instead of turn over turn advantage.\
That is the deck I am keeping a list of right now that isn't just built out of my Commander box when I feel like making something.
My goal typically with Meltdown is to cast it for less than an overloaded Vandalblast would be it is for like X=2 or 3 a version of this running vandal blast may be running more artifact ramp.

Stuff that Didn't make the Cut
Crypt Ghast and/or Bubbling Muck - I like the idea of these but it gets hard finding room for them.
High Tide + Realmwright and/or Prismatic Omen
Time Spiral - I like having a graveyard but I still probably should make room for this monster
Stuff I specifically stayed away from
Extra Turns, they could slot in very easily but I more want to build one massive turn instead of turn over turn advantage.\
That is the deck I am keeping a list of right now that isn't just built out of my Commander box when I feel like making something.
(U/B)(U/B)(U/B) JUMP IN THE LINE, ROCK YOUR BODY IN TIME
(R/W)(R/W)(R/W) RISING FROM THE NEON GLOOM, SHINING LIKE A CRAZY MOON
(U/R)(R/G)(G/U) STEALIN' WHEN I SHOULD HAVE BEEN BUYIN'
My goal typically with Meltdown is to cast it for less than an overloaded Vandalblast would be it is for like X=2 or 3 a version of this running vandal blast may be running more artifact ramp.
