New set with goodies!
Gideon's Phalanx
5 W W
Instant
Put four 2/2 white Knight creature tokens with vigilance onto the battlefield.
Spell mastery — If there are two or more instant and/or sorcery cards in your graveyard, creatures you control gain indestructible until end of turn.
This seems fine, it's 8 power as an instant, so you can easily sneak that EOT, and the added indestructible can come in handy.
Displacement Wave
X UU
Sorcery
Return all nonland permanents with converted mana cost X or less to their owners' hands.
This seems about as good as upheaval. It doesn't bounce lands, but you can use it to only bounce small stuff and attack with big things.
Talent of the Telepath
2 U U
Sorcery
Target opponent reveals the top seven cards of his or her library. You may cast an instant or sorcery card from among them without paying its mana cost. Then that player puts the rest into his or her graveyard.
Spell mastery --- If there are two or more instant and/or sorcery cards in your graveyard, you may cast up to two revealed instant and/or sorcery cards instead of one.
This looks soooo fun, auto-include in all stacks.
Kothophed, Soul Hoarder
4 B B
Legendary Creature - Demon
Flying
Whenever a permanent owned by another player is put into the graveyard from the battlefield, you draw one card and lose 1 life.
6/6
Seems not bad at all. Should allow you to draw 2-3 and it has a big body.
Unholy Hunger
3 B B
Instant
Destroy target creature.
Spell mastery — If there are two or more instant and/or sorcery cards in your graveyard, you gain 2 life.
Simple, efficient.
Flesh to Dust
3 B B
Instant
Destroy target creature. It can't be regenerated.
Same, but a bit boring, there are probably enough of those already.
Flameshadow Conjuring
3 R
Enchantment
Whenever a nontoken creature enters the battlefield under your control, you may pay R. If you do, put a token onto the battlefield that's a copy of that creature. That token gains haste. Exile it at the beginning of the next end step.
Not totally broken, but pretty fun!
The Great Aurora
6 G G G
Sorcery
Each player shuffles all cards from his or her hand and all permanents he or she owns into his or her library, then draws that many cards. Each player may put any number of land cards from his or her hand onto the battlefield. Exile The Great Aurora.
New effect to sweep the board, albeit maybe at a card disadvantage. Worth a try.
Nissa's Revelation
5 G G
Sorcery
Scry 5, then reveal the top card of your library. If it's a creature card, you draw cards equal to its power and gain life equal to its toughness.
This will be at least a draw 5 gain 5 life most of the time, with the added scry. Seems pretty damn good.
