The recycling also ensures you don't deck yourself in a long game. Once you've completely taken control you can think about winning. You might play Fireball and recycle it with Gaea's Blessing, attack with Uktabi Orangutans, or simply counter everything while recycling your own cards, and wait for your opponent to run out of cards. Beating the Deck D 5C's biggest weakness is its land. A second-turn Dwarven Miner means an almost certain defeat, since D5C may never reach four mana to cast Wrath of God.
Wasteland is also very strong against it.
A fast attack is still the most difficult strategy for D5C to deal with, even with Walls of Blossoms in the deck. If your opponent doesn't draw Wrath of God or Gerrard's Wisdom, or if you can stop those spells, you can win before the deck gets established. Creatures with shadow or flying allow you to ignore Walls, while River Boas may be able to islandwalk past them. Creature decks that recycle cards from their graveyards can also give it a hard time. A good permission deck may be able to out-counter the D5C deck, provided it can counter Gaea's Blessing.
