You may tap two untapped red creatures and/or planeswalkers you control with different names rather than pay this spell's mana cost.
Exile the top two cards of your library. Until the end of your next turn, you may play those cards.

Counter up to one target spell unless its controller pays {2}. Until end of turn, you may cast spells as though they had flash.

Flying, vigilance

When Conscious Taboo enters, look at target opponent's hand. You may exile a noncreature, nonland card from it. For as long as that card remains exiled, its owner may play it. A spell cast this way costs {2} more to cast.

{T}: Add {R} or {W}.
{T}, Sacrifice Sigil of Brutality: Add {R}{W}.

Flash (You may cast this spell any time you could cast an instant.)
Flying (This creature can't be blocked except by creatures with flying or reach.)

{2}{R}: Ruthless Mastiff gets +3/+0 until end of turn.

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.)

Prowess
Whenever you cast your first instant or sorcery spell from your hand during each of your turns, if it doesn't have compose, it gains compose. (Then if you cast this from your hand, exile it and create a Saga token with “r3—You may cast a copy of this card from exile without paying its mana cost.”)

Solar Pulse deals 3 damage to target attacking or blocking creature.

({T}: Add {W}.)
Moon of the Final Dawn enters tapped.
{1}{W}, {T}: Scry 1.

When Kinsang Butcher enters, create a Treasure token.
{1}, Sacrifice an artifact or another creature: Put a +1/+1 counter on Kinsang Butcher. Activate only as a sorcery.

Each player chooses up to one permanent they control of each permanent type, then sacrifices the rest. (The permanent types are artifact, creature, enchantment, land, and planeswalker.)

As an additional cost to cast this spell, you may pay {1}{R}.
Put a double strike counter on target creature you control.
If this spell's additional cost was paid, untap each creature you control that attacked this turn instead. After this main phase, there is an additional combat phase followed by an additional main phase.

This creature gets +1/+0 and has indestructible as long as another Knight or Soldier entered under your control this turn.

Melee (Whenever this creature attacks, it gets +1/+1 until end of turn for each opponent you attacked this combat.)
Whenever Knight of the Cockatrice attacks, you may pay {1}{R}. When you do, target creature can't block this turn.

When this creature enters, draw a card, then put a creature you control on top of its owner's library.

At the beginning of your upkeep, choose one —
• Create a colorless artifact token named Etherium Cell with “{T}, Sacrifice this artifact: Add one mana of any color.”
• Put a +1/+1 counter on another target artifact. It becomes a 0/0 Construct artifact creature if it isn't a creature.

Scry 3.
Catalyze. (The next spell you cast this turn costs {1} less to cast.)

Destroy all creatures, then return all nonland permanents to their owner's hands.

I — Create a 1/1 green Insect creature token.
II — Create a 2/2 white Cat creature token.
III — Create a 3/3 red Ox creature token.
IV — Creatures you control gain vigilance and indestructible until end of turn.

First strike

Destroy target creature. You may remove a counter from up to one target permanent.

Gain control of target creature until end of turn. Put a +1/+1 counter on it and untap it. That creature gains haste until end of turn.

Search your library for up to two basic land cards, reveal them, put them into your hand, then shuffle.
You may put up to two land cards from your hand onto the battlefield tapped.
