White-black-green brings forth the other direction: a deck which couldn't have existed beforehand or only using main-set cards but works precisely because we made a deck for it
(2016-04-08) Because you consider only the characteristics of a double-faced card's front face while it's not on the battlefield, the types of its back face won't be counted for delirium
Thats right, Archangel Avacyn then becomes Avacyn, the Purifier
Invasive Surgery is cheap but requires delirium to be an extraction effect, Counterbore is more expensive but a counterspell to any card type, and Quash is just a more expensive version of Test of Talents
The best Simic creatures take those traits so far that they must be answered, or that answering them once isn't good enough because they were a two-for-one
Its so ubiquitous that its banned in every format except Commander (its a key piece in the best Commander decks) and Vintage, where its restricted to just one copy
