The combo seems weird...i guess i never would've encountered it. Very cool though. Considering you have like thirty targets for it, either Commune with the Gods or Benefaction of Rhonas might be useful.

"The combo seems weird"

Well, I certainly won't argue with that assessment. Thanks for the suggestions, seshiro_of_the_orochi.

I've only toyed around with the deck for a bit once I saw it (SUPER sweet by the way, I love it). But I found that a chunk of the time I had the combo set up and ready to go with huge amounts of mana, communes in hand, fecundity in play, but to get the combo started, I'd have to spend a lot of my colored mana, then I wouldn't be take advantage of the colorless mana I'd generated since I couldn't cast the rest of the combo.

It's entirely possible that my lack of experience makes it so that I'm improperly setting up the combo, but I might suggest some mana filtering artifacts commonly seen in this kind of deck: Chromatic Sphere and Chromatic Star. They additionally can fill awkward gaps in your early turns since I notice you don't have any 1-drops at all.

Also, I'm not sure if this format allows sideboards, but if it does, just put a finisher or two in it, because Spawnsire of Ulamog's second ability can be utilized to get cards from your sideboard as per official rulings, making it both an integral combo piece AND your finisher. The bonus points are that you're even still casting them and get all such cast triggers.

No, it's not just the way you're playing it, Enganeer; a lack of coloured mana is often the limiting factor in a turn. Thanks for the suggestions, I'll see if I can figure out a way to squeeze them in. Also, sideboards aren't allowed in Tribal Wars, unfortunately, so no wish-boarding for me.

Heyhey! I just looked it up and it appears that wish cards actually work RAW in tribal wars format. When you use Spawnsire of Ulamog's 2nd ability, you are in fact allowed to take any number of Eldrazi cards that you have in your collection and cast them without paying their mana cost!

Go, fill your collection with Eldrazi (they don't even have to be the big scary legendary ones). There are eldrazi that do everything, so if an Emrakul doesn't beat Ensnaring Bridge, Glacial Chasm or what have you, Ulamog, the Ceaseless Hunger and World Breaker are your best friends.

That, unfortunately, also won't work. I play on MTGO and the program just isn't able to let you wish for things outside of the sideboard.
