Inkwell Leviathan 8 This is the other Simic Sky Swallower and is a big part of why we see less of the big fish in cheat in focused decks (that is one of the nice things about Sky Swallower in the cube in general, it is something you can just play at the top end of a normal deck and it gets about half of its play in that manner)
Thoden, King of Rohan Thoden, King of Rohans ability to give creatures double strike for a turn can make your attackers a lot more dangerous
