Creatures you control with +1/+1 counters on them can’t be blocked.
Magecraft — Whenever you cast or copy an instant or sorcery spell, draw a card.
Flying {1}{U}, {Q}: Target opponent exiles the top card of their library. Until end of turn, you may play that card. ({Q} is the untap symbol.)
As Reflections of Littjara enters, choose a creature type. Whenever you cast a spell of the chosen type, copy that spell. (A copy of a permanent spell becomes a token.)
Counter target spell. Create X Treasure tokens, where X is that spell’s mana value. (They’re artifacts with “{T}, Sacrifice this artifact: Add one mana of any color.”)
Search target opponent’s library for an artifact card and put that card onto the battlefield under your control. Then that player shuffles.
Whenever an opponent casts a spell, you may exchange control of Perplexing Chimera and that spell. If you do, you may choose new targets for the spell. (If the spell becomes a permanent, you control that permanent.)
The Watcher in the Water enters tapped with nine stun counters on it. (If a permanent with a stun counter would become untapped, remove one from it instead.) Whenever you draw a card during an opponent’s turn, create a 1/1 blue Tentacle creature token. Whenever a Tentacle you control dies, untap up to one target Kraken and put a stun counter on up to one target nonland permanent.
End the turn. (Exile all spells and abilities, including this spell. The player whose turn it is discards down to their maximum hand size. Damage heals and “this turn” and “until end of turn” effects end.)
Surge {3}{U}{U} (You may cast this spell for its surge cost if you or a teammate has cast another spell this turn.) Return all nonland permanents to their owners’ hands. If this spell’s surge cost was paid, create an 8/8 blue Octopus creature token.
Myojin of Seeing Winds enters with a divinity counter on it if you cast it from your hand. Myojin of Seeing Winds has indestructible as long as it has a divinity counter on it. Remove a divinity counter from Myojin of Seeing Winds: Draw a card for each permanent you control.
Each other Wizard creature you control enters with an additional +1/+1 counter on it. {2}, Remove a +1/+1 counter from a creature you control: Draw a card.
Whenever a spell or ability you control counters a spell, you may create a 1/1 blue Merfolk creature token. Tap seven untapped Merfolk you control: Counter target spell.
Other blue creatures you control get +1/+1. {U}: Target artifact creature becomes blue until end of turn. Tap an untapped blue creature you control: Add {C}{C}. Spend this mana only to cast artifact spells or activate abilities of artifacts.
Other blue creatures you control get +1/+1. {U}: Target artifact creature becomes blue until end of turn. Tap an untapped blue creature you control: Add {C}{C}. Spend this mana only to cast artifact spells or activate abilities of artifacts.
