Quantity over quality! Since you never know what you are going to get with evolve, it's best to have lots of chances.

Murmuring Elemental works great with almost everything. See list:
+Firefly = 2x Flame Elemental
+Pantry Spider = 2x 1/3 Spiders
+Master of Evolution = target "evolves" +2 levels instead of 1
+Lotus Agent = discovers twice
+Big-Time Racketeer = get 2 6/6 Little Friends

+Yogg-Saron, Hope's End = double spell barrage - while this is super impressive and very difficult to pull off (only possible with Far Sight), it probably is not worth it since he will likely just kill himself.

Spells bring down the cost of Arcane Giant and totems reduce Thing from Below

Feral Gibberer is great first turn drop against anyone except mage.

FINALLY got Thrall, Deathseer from Frozen Throne and added him to deck (yes, new rotation starts in just a few days, just my luck)
