Exile the top two cards of your library. Until the end of your next turn, you may play those cards. (If you cast a spell this way, you still pay its costs. You can play a land this way only if you have an available land play remaining.)

As an additional cost to cast this spell, put a card from your hand on the bottom of your library.
Draw two cards.

Deathtouch
Whenever Ruststep Centipede deals combat damage to a player, you may destroy target artifact or enchantment that player controls.

Whenever you cast a spell from anywhere other than your hand, return Ruthless Bakhtak from your graveyard to your hand.

When Ruthless Conscript dies, arm up to two target creatures you control. (Create a colorless Equipment artifact token with “Equipped creature gets +1/+0” and equip {2}, then attach it to that creature.)

Whenever a Survivor you control dies, target creature you don't control gets -1/-1 until end of turn.

When Ryleth, Vengeful Shadow enters, create two 1/1 green Elf creature tokens.
Whenever you attack, you may pay {1}{B/G}. When you do, return target creature card with mana value less than or equal to the number of attacking creature tokens you control from your graveyard to the battlefield tapped and attacking.

When Sable Evangelist enters, create a 0/1 black Cultist creature token with “{1}{B}{B}, Sacrifice three Cultists: Create a 5/5 black Demon creature token.”
Cultists you control get +2/+0 and can't block.

Enchant creature
Enchanted creature gets +3/+3 and has flying and vigilance.
Lifecycle {3} ({3}, Discard this card: Create two tapped 1/1 colorless Elemental creature tokens.)

Search your library for an Equipment card, reveal that card, put it into your hand, then shuffle.
Monument {3}{W} (You may cast this transformed from your graveyard for its monument cost. Exile it if it would leave the battlefield or not resolve.)

Sacred Summits enters tapped.
{T}: Add one mana of any color among the color identity of legendary creatures and planeswalkers you control or legendary cards in your command zone.

Target creature gains indestructible until end of turn.
Fuse (You may cast one or both halves of this card from your hand.)

When Saffrisa's Darkcaster enters, look at the top four cards of your library. You may substantiate a card from among them. Put the rest into your graveyard. (To substantiate a card, put it onto the battlefield face down as a 2/2 creature. You may turn it face up and cast it at any time for its mana cost if it isn't a creature.)

Whenever a creature dies, each opponent loses 1 life and you gain 1 life.
At the beginning of your end step, if you gained 4 or more life this turn, you may sacrifice Saffrisa's Touch. If you do, return target creature card from your graveyard to the battlefield.

Whenever a creature in Sage of Circular Motion's pack becomes the target of a spell, draw a card. (Two or more creatures you control with equal power are in a pack.)

Flying
When Sage of Storms enters, untap another target creature you control with flying and put a +1/+1 counter on it.

Whenever you draw a card, put a +1/+1 counter on Sage of Wilds.
Augmented — {T}: Scry 1, then draw a card. Activate only if you've spent {W}{U}{B}{R}{G} to cast spells this turn.
