hmm... it does have the capability to give all your creatures +6/+6 and your opponents +1 +1... and if you have 3 more creatures than he does (from playing green).. that might be a little better than GG...
3G might be a better idea... cause by that time each player should have at least a couple creatures..
T1: Forest, Birds
opp1: Swamp, Carnophage
T2: Forest, Llanowar, Priest of Titania
opp2: Swamp, Ritual, Erg Raiders, Blind Creeper
T3: Forest, tap for 7 green.. 4 for brownies
opp3: roll brownies.. SWEET!!! +6/+6 um.. hehe ok...
ill attack with my 8/8 carnophage.. my 9/8 erg raiders, and my 9/9 blind creeper..
you: hmm.. im tapped out... game...
i dunno.. i think it needs to be more but not much.. 4 is too much.. a thing GGG is a good cost... that way you cant do splash.. or ill make it 2GG
T1: Forest, Birds
opp1: Mountain
T2: Forest, Llanowar, Priest of Titania
opp2: Mountain, Okk (holding a bolt)
T3: Forest, tap for 7 green.. 4 for brownies
opp3: roll brownies.. SWEET!!! +6/+6 um..
Mountain, Ball Lightning.. attack with a 12/1 trampler, and a 10/10 Okk..
this card totally ends the game... it almost reads
whoever has the most untapped creatures will ultimately win..
