Here's my current decklist for post rotation. Not liking my chances with the new tribal nerf coming out, but we'll see what it can do.
I'm leaving in the blue, despite your concerns. Why, you may ask? Because the deck is actually pretty consistent and can go to 5 and still win without much trouble. Honestly Risen Reef is one of the win conditions of this deck because it generates so much value so quickly with the other cards in here. And once I hit two I can quickly end the game from there. On top of that Thunderkin Awakener can revive them, which opens up some really cool possibilities, meaning it doesn't hurt me as much if I lose one or two early on to removal.
Honestly Awakener is just disgusting in this deck. Between the combos with Scampering Scorcher and Risen Reef and how busted it can get with Omnath in play, It has the potential to generate a ton of value late game.
Example: Risen Reefs and Thunderkin Awakener, Omnath in graveyard and in hand. Cast Omnath, punch biggest creature, get two lands in play, Pump Awakener twice, combat, bring in Dead Omnath and sac him to Legendary rule, but not before getting two more Risen Reef triggers and punching something else in the face.
And that's just one example of this deck popping off.
