Tribal Unity

Yes i agree, but even better for my elf deck is taht you get priest of titanias out which is when you tap it it gives x green mana for how many elves in play so i used taht tapped a few llanowars and i was up to like 30/30s with everything.

Very good. Period. Centaur Glade + Tribal Unity + Tribal Forcemage's morph ability+Mana production. 20/20 green centaur tokens with trample. Tribal Unity is my friend's most-hated and most-wanted card, just because of this little combo.

Ok in a elf deck (which i use) This is a AWSOME CARD, its affordable, and down right good. The way I use wirewood channelers with this, and have average of 5 elfs in play by time wirewood hits the ground,plus likely have 10 mana already ( elfs with tap and gain 1 mana to mana pool) Use wirewood to get 15, then basically all elfs in my hand go down... thats about 7, then tap it again 22. Tribal unity pops up. BAM use it, All elfs get 19/19 (cost 3 to play and tap the other 19 lands) With 7 elfs,even if 1/1 now become 20/20 Most likely your opponent wont have more that 6 creatures.And if their a wall deck.... you just destroyed their defense :)
