Note that the wincons also can serve as creature removal, which is why so many of the outs are instant/sorcery removals In: Haven of the Spirit Dragon (creature recursion), 3 Mountain (31 lands is not enough - will miss land drops too often and its vital that the commander come down ASAP - nick loses too many times by not getting threats out in time) In: Cinderclasm (better than blazing volley), Shenanigans (reusable artifact destruction, combos with Liquimetal Torgue), Chaos Warp, Mizzium Mortars (one sided boardwipe) In: Gadrak, the Crown-Scourge, Taurean Mauler, Dragonkin Berserker, Dragonmaster Outcast, Molten Echoes, Minion of the Mighty, Sunbird's Invocation
