put lure and regeneration on brookhatch...atack...regenerate...next turn...tribal unity

enchat the channeler with pemins aura and alot of mana use trbal pump up a creature type and attack

get a bunch of elves in play...tap enchanted land (enchanted with elvish guidance) then play tribal unity...choose elf... massive elf attack.

simple enough

morph branchtop lorian then choose beasts for tribal unity and attack with your morph creature then unmorph branch top lorian for 1 mana and he'll be a lot stronger

play the hivemaster and then some small costing elves (like llanowars) and the forcemage face down. morph it then play tribal unity and give your insect tokens x/x and trample. great sneak attack!

your elves will gain at least +15+15 untill the end of turn(it will depend on the mana you have out and the number of elves

commander turns lands into 1/1 elf creatures. tap land/elf to play unity. each land/elf gets +x/+x til end of turn. cast vitalize to untap all land/elf & attack
