MTG Salvation

Nightmare Lands 1B
Enchantment - Aura
Enchant Swamp
Enchanted Swamp has "2B,T: Target player discards 2 cards."
Sacrifice ~: Target player discards a card.

Next: Captive of the Realm

You posted slightly before me. I had to edit it for G, instead of F.

Edit:

Great Pit of the Dead
Land
T: Add 1 to yoru mana pool.
2B,T: Put a 2/2 black Zombie creature token into play under your control.

Silent Crash 2UW
Instant
Counter target spell. Instead of putting it in that player's graveyard, that player exiles it instead.
Draw a card.

Next: Ertai's Eight Spells

Treetop Stalker 3G
Creature - Elf Ninja
Ninjutsu 1G
GG: ~ is unblockable until end of turn.
2/2

Next: Starfish Monk

Allhigh Peak
Land
T: Add 1 to your mana pool.
Creatures you control have Reach.

Firecackle Imp 2BR
When ~ comes into play, discard a card.
Threshold - As long as seven or more cards are in your graveyard, ~ has flying.
Hellbent - As long as you have no cards in your hand, ~ gets +3/+3
Unearth BR
2/1

Next: Fading, Morph

Wild Ceeldoborn UG
Creature - Lizard Mutant
Shroud
As an additional cost to play ~, sacrifice an Enchantment.
Normally reclusive, the Ceeldoborn is often drawn from the wild to the city, where the smell of Auras is especially strong.
3/3

Next: XBBBBW

Mountaincrasher 1RR
Creature - Elemental
Haste, Trample
As an additional cost to play ~, sacrifice a mountain.
Whenever ~ deals combat damage to an opponent, sacrifice a mountain. If you cannot, sacrifice ~.
5/3

Quote from Illuminations

Shedding Nantuko 1BG
Creature - Insect Druid Warrior
1BG, Sacrifice ~: Put a token that's a copy of ~ onto the battlefield.
When it comes shedding time, Nantukos leave their skins as decoys on the battlefield.
3/2

(This card was created long before the M10 rules. The M10 rules nerf this severely.)

Art: Spear in hand, a Nantuko watches from a treetop as several goblins investigate another of his kind on the forest floor--this one with a gaping, jagged hole in its back.


__________ 2UUR
Legendary Creature - ___________
T: Until end of turn, Instants and Sorceries you play cannot be countered.
______________
2/3

Then perhaps I should change it to:

Stolen Spell 3U
Enchantment
Whenever a player draws a card, he or she must reveal that card. Any player may play that card for X, where X is that card's converted mana cost. If two players want to play the card, then in turn order each player may bid mana. The bidding ends if the high bid stands. The highest bidder must spend that much additional mana to play the spell.

Garrugavec seems pretty good, and he seems pretty balanced because he needs to take a break in between attacks, but this gives him an uncommon source of evasion.

I liked the Zombie card, as he would be great with Buried Alive. I could easily see him getting recognition in zombie decks.

Is the last part of (Wrong!) supposed to be "Otherwise add it to your hand and copy ~. ? If so, I would think it to be way to unbalanced. You could easily snag 5 cards this way, and maybe even more if you are lucky. Also cards like Wizened Snitches make that card useless, because when you put the cards back on top, your opponent still is allowed to see it, essentially destroying the card's effect.

Flathernut UR
Creature - Fox Crab
You may sacrifice an Island or Mountain instead of playing Flathernut's mana cost.
Whenever you draw a card, you may reveal it. If it's cardname is Flathernut, you may put that card into play under your control.
The goblins soon learned that Flathernuts are notorious for their ability to congregate...quickly.
2/1

Next: Slug Mercenary

Fate's Herald 2W
Creature - Spirit Soldier
Fate's Herald gets +1/+0 as long

Mogg Bridgebreaker 1RR
Creature - Goblin Berserker
Lands that are tapped when ~ comes into play do not untap during their controller's next untap step.
Sadly, most bridges look identical to goblins.
3/3
