here's my version of the speed rainbow deck:
notable alterations include:
out: 1x graboid
in: 1x pulverizer
more permanent destruction is necessary to deal with so many hourglasses and sundials in the t50.
out: fire specter
in: graviton firemaster
i like that it stays on the board longer with the extra hp.
out 2x thunderbolt
in: 2x congeal
doesn't matter how many hp the creature has, and you should have the game in hand by the time it unfreezes. speed poison utilizes this card well, and so can this deck.
out: improved steal
in: twin universe
the advantages of using TU have already been discussed earlier in the thread. cutting the thunderbolts makes it an easy include.
out: eagle's eye
in: elite queen
pulverizer is the current weapon of choice, and the queen can accumulate damage pretty quickly. this puts the deck a little low on creature removal, but that doesn't seem to be too much of a problem. i had pulvy and EE in the deck for quite a while and i always found myself with the EE sitting dead in my hand because i needed to destroy a sundial every turn.
archangel is a decent damage card. it tends to draw damage to itself which it can heal, or it can allow graboid to stay above ground against something like an EE. also, bonewall was removed as it has no synergy with this decks complete lack of ability to remove a creature from the board as well as its offensive strategy. the deck currently doesn't use anything from the death element. none of the cards seem to fit well enough even if the cost is effectively nothing as the reduction in card quality seems too great.
