Double strike

Your opponents can't cast spells during combat.

Whenever a creature you control deals combat damage to a player, goad each creature that player controls. (Until your next turn, those creatures attack each combat if able and attack a player other than you if able.)

At the beginning of your upkeep, put a +1/+1 counter on each creature you control if you control a creature with power 5 or greater. Then you gain 10 life if you control a creature with power 10 or greater. Then you win the game if you control a creature with power 20 or greater.

Creature tokens you control have haste.

Parley -- At the beginning of combat on your turn, each player reveals the top card of their library. For each land card revealed this way, you create a 1/1 green and white Citizen creature token. Then creatures you control get +1/+1 until end of turn for each nonland card revealed this way. Then each player draws a card.

Whenever you cast a Dog spell, create a 1/1 green Cat creature token.

Whenever you cast a Cat spell, create a 1/1 white Dog creature token.

{R}{G}{W}, {T}: Rin and Seri, Inseparable deals damage to any target equal to the number of Dogs you control. You gain life equal to the number of Cats you control.
