one piece card game japan Kingdoms of Intrigue Japanese Booster Box OP-04 Boxes are sealed with a small piece of tape on the top flap ONE PIECE CARD GAME Japanese

Its close to free and does the job many maindeck cards like Archaeomancer would already be doing

Gideon, how easy it must be to play the protector when you think yourself untouchable

You also don't have to choose between doing direct damage or attacking a planeswalker when you're attacking with it thanks to its triggered ability

There is almost zero downside is doing this now

I'm not sure about the status of your playgroup, but I also would suggest sweepers like Cataclysm, Tragic Arrogance, Mutilate, Cyclonic Rift, basically any sweeper that says "Sacrifice", "Bounce" or "-X/-X" to account for cards like Avacyn, Angel of Hope

Taking a combo piece or piece of interaction while keeping the pressure up can be the difference in the game
