My version tries to play like a U/W Control deck that draws cards along the way, counters problematic spells, and eventually wins through overwhelming card and mana advantage, both of which are provided by protecting Brago and extracting as many blinks out of him as you possibly can
You can play with just a 60 card deck but there are a lot more things around it that will help to improve your game and, most importantly, maximise your fun
Yes it is, according to WotCs post on the warp mechanic
However, there are also a certain few cards that can be contained through other means, outside of ripping packs or purchasing with Pack Points
This pairs perfectly with both Madam Mim cards, which can return a character in play back to your hand when played, meaning you get to activate any Giant Cobra once again
