This deck easily won 2 of 2 matches tonight against mono-green Tribute Devotion.

Kabira Evangel + Aether Vial on an opponent's turn means you can protect Harabaz Druid all the time so long as you have Allies to play.

I love the concept of this deck, but it is def not going to be easy to make it work well. You have some obvious needs in 1) getting the combo pieces 2) having enough mana to cast them all before your opponent stops you 3) having room for defense and removal and 4) making sure your cloaked creatures die.

1) You not only need have some way of assembling your combo, you also need a way to put a spell on top of your library. I have to do this with my deck Cover Girl. The only spells I could find that made sense in that deck were: Jace, the Mind Sculptor, Brainstone, and Scheming Symmetry. I suggest running 2x of each of the first. Scheming Symmetry is a pretty big risk, so I advise against that here. The upshot of Jace is that you can cycle through your library 3 cards at a time, so you not only get to control your top card, you also get to filter for what you need.

2) Provided you employ some added filtering with Jace and Brainstone, I think you can remove some of your extra threats. This will allow for a little ramp. I guess I'd probably go with Birds of Paradise unless you're worried it will get bolted for being a bird. Then I'd probably go with a land enchantment like Fertile Ground. I think with the high-ish cost of your combo pieces, a little ramp is going to be helpful in creating a consistency in speed. (not to be fast, just to be as fast as it can be more reliably)

3) It occurs to me that cloaked spells could be blockers IF you both don't have all the combo pieces in place AND you whiffed with Hide in Plain Sight. Those are somewhat narrow conditions, so it's probably best not rely on that. I see you have room for 35 more cards, approx 24 of which will probably be lands, so I'll have to wait and see how much room you have for more defense and removal, but I think you have to include Bone Splinters. It's not as fast as I'd like but it pulls double duty in kicking off the final step in your combo and it does it for 1 MV instead of 3 like Start / Finish. I'd probably throw in 1x Fog, too. And Assassin's Trophy and Abrupt Decay would be excellent additions to the mainboard and sideboard. I'd probably go 4xBone Splinters, 2xAssassin's Trophy, 1xAbrupt Decay in the main and then extra of the instants in the sideboard.

4) Bone Splinters helps make sure you creatures die, but a board wipe like Killing Wave would probably be useful as well late game.

I suggest adding in some protection and removal spells. Perhaps 4xHyena Umbra in place of 2xForced Adaptation and 2xGleam of Authority and 4xRam Through in place of Giant Growth

Thanks so much for the +1, KIllStreak415!
