At the beginning of your upkeep, you may exchange control of target nonland permanent you control and target nonland permanent an opponent controls with equal or lesser mana value.
Counter target spell. If that spell is countered this way, put that card on the top or bottom of its owner’s library instead of into that player’s graveyard.
End the turn. (Exile all spells and abilities from the stack, including this card. The player whose turn it is discards down to their maximum hand size. Damage wears off, and “this turn” and “until end of turn” effects end.)
You may look at the top card of your library any time. You may play lands and cast spells from the top of your library. Once during each of your turns, you may cast a spell from your hand or the top of your library without paying its mana cost.
Exile target creature and put two time counters on it. If it doesn’t have suspend, it gains suspend. (At the beginning of its owner’s upkeep, they remove a time counter. When the last is removed, they may play it without paying its mana cost. If it’s a creature, it has haste.)
Each opponent can’t draw more than one card each turn. −2: Look at the top four cards of your library. You may reveal a noncreature, nonland card from among them and put it into your hand. Put the rest on the bottom of your library in a random order. Loyalty: 5
As Xenograft enters, choose a creature type. Each creature you control is the chosen type in addition to its other types.
Whenever Cephalid Constable deals combat damage to a player, return up to that many target permanents that player controls to their owner’s hand. 1/1
Kicker {5} (You may pay an additional {5} as you cast this spell.) Create a token that’s a copy of target creature. If this spell was kicked, create five of those tokens instead.
Counter target spell, activated ability, or triggered ability. (Mana abilities can’t be targeted.)
Hunted Phantasm is unblockable. When Hunted Phantasm comes into play, put five 1/1 red Goblin creature tokens into play under target opponent’s control.
Protection from red Elemental creatures you control get +1/+1. When Master of Waves enters the battlefield, create a number of 1/0 blue Elemental creature tokens equal to your devotion to blue. (Each U in the mana costs of permanents you control counts toward your devotion to blue.)
This spell costs {1} less to cast for each artifact you control. When Emry, Lurker of the Loch enters, mill four cards. {T}: Choose target artifact card in your graveyard. You may cast that card this turn. (You still pay its costs. Timing rules still apply.)
