max potion pokemon card - 128/145 (SM:GRI) Uncommon discard all Energy from that Pokémon Pokemon Trading Card - Emerging

The Armada Wurm is 10 power, with trample, across two creatures, for six mana

This whole interaction of shuffling your library after you play Brainstorm is very common, and one of the main reasons to play this blue spell

Maybe if Deep Water turned all your lands into Islands, it would matter for cards like Engulf the Shore, Scourge of Fleets, or Vedalken Shackles

You have things like Quickling to protect your dorks while Cavern Harpy is on the stack and acts as important redundancy there

So Im a very enfranchised player, and if I hadnt looked up Commander ninjutsu ahead of time, I would have been uncertain about it when I first saw this card in a draft
