This is a bit of an odd duck. I included Inexorable Tide in an otherwise entirely green deck, but I have 9 cards that allow me to get the mana I need, 6 of which increase production. Most creatures here have Infect, and the Giant Growth and Berserk bonuses can make that nastier than usual. Unlike black creatures with infect, though, many of these have side benefits. It has a flat-ish curve at 14-7-8-6-5, but since a half dozen at the 1-spot increase mana, this may be OK. The average is still up there at 2.53, though. Ideally, I would Berserk a big creatures and end things, but that is not likely even half of the time. Instead, a poison counter followed by some Inexorable tide action should do. I might consider a third Phyrexian Hydra in a later version, but I will try this for now.
