snorlax doll pokemon card #175/182 RH Counter Catch, Noroi no Hataki,

During a game, at the bottom of the screen, you can select to add a "stop" during various turn phases to create the illusion that you have a card to play in response

While normally this would leave a one turn gap in which Mewtwo needs to recharge, Gardevoir accelerates this by letting you attach two Psychic Energy per turn

The attack form's Psyspear attack can launch 120 damage attacks that also snipe the opponent's bench, but you'll need five total energy cards attached to it before you can take advantage of this

If you want to maximize the potential for building a synergistic deck, Id suggest starting there

Ryu is quite flexible in terms of his overall playstyle in Commander
