Secret Lair x SpongeBob SquarePants: Legends of Bikini Bottom

Plankton, Tiny Tyrant (Skrelv, Defector Mite)

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.) Skrelv can't block. {W/P}, {T}: Choose a color. Another target creature you control gains toxic 1 and hexproof from that color until end of turn. It can't be blocked by creatures of that color this turn. ({W/P} can be paid with either {W} or 2 life.)

Mr. Krabs, Penny Pincher (Charix, the Raging Isle)

Spells your opponents cast that target Charix cost {2} more to cast. {3}: Charix gets +X/-X until end of turn, where X is the number of Islands you control.

Squidward, Sarcastic Snob (Grazilaxx, Illithid Scholar)

Whenever a creature you control becomes blocked, you may return it to its owner's hand. Whenever one or more creatures you control deal combat damage to a player, draw a card.

Gary, the Snail (Toxrill, the Corrosive)

At the beginning of each end step, put a slime counter on each creature you don't control. Creatures you don't control get -1/-1 for each slime counter on them. Whenever a creature you don't control with a slime counter on it dies, create a 1/1 black Slug creature token. {U}{B}, Sacrifice a Slug: Draw a card.

Sandy Cheeks, Martial Astronaut (Toski, Bearer of Secrets)

This spell can't be countered. Indestructible Toski attacks each combat if able. Whenever a creature you control deals combat damage to a player, draw a card.

Patrick Star (Barktooth Warbeard)

SpongeBob SquarePants (Jodah, the Unifier)

Legendary creatures you control get +X/+X, where X is the number of legendary creatures you control. Whenever you cast a legendary spell from your hand, exile cards from the top of your library until you exile a legendary nonland card with lesser mana value. You may cast that card without paying its mana cost. Put the rest on the bottom of your library in a random order.
