When Augur of Bolas enters, look at the top three cards of your library. You may reveal an instant or sorcery card from among them and put it into your hand. Put the rest on the bottom of your library in any order.
Toxic Iguanar has deathtouch as long as you control a green permanent. (Any amount of damage a creature with deathtouch deals to a creature is enough to destroy it.)
When First-Sphere Gargantua enters, you draw a card and you lose 1 life.Unearth (: Return this card from your graveyard to the battlefield. It gains haste. Exile it at the beginning of the next end step or if it would leave the battlefield. Unearth only as a sorcery.)
Exploit (When this creature enters, you may sacrifice a creature.)When Silumgar Butcher exploits a creature, target creature gets -3/-3 until end of turn.
FlyingDeathtouch (Any amount of damage this deals to a creature is enough to destroy it.)Lifelink (Damage dealt by this creature also causes you to gain that much life.)
Kicker (You may pay an additional as you cast this spell.)Create two 1/1 green Saproling creature tokens. If this spell was kicked, create four of those tokens instead.
Backup 1 (When this creature enters, put a +1/+1 counter on target creature. If that's another creature, it gains the following ability until end of turn.)This creature assigns combat damage equal to its toughness rather than its power.
FlyingWhenever Thrummingbird deals combat damage to a player, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)
Convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays for or one mana of that creature's color.)Vigilance
Regenerate target creature. Draw a card. (The next time the creature would be destroyed this turn, instead tap it, remove it from combat, and heal all damage on it.)Spell mastery — If there are two or more instant and/or sorcery cards in your graveyard, also regenerate each other creature you control.
