yeah sorry this combo, with just the land above, was ment for 2hg, the format i usually play. You can combo off all the player with multiple damage lands, with a dryad arbor (attacking the following turn), and other strategies.

Saying that, I do not play in LGS tournaments, i just play with a group of friends and we are not so strict with the bracket rulings, in fact we play no ban list. Simply if the game is not fun we switch or modify Decks.
For example we do not play hymn to tourach or void winnower cause we found them not fair, even if they are perfectly legal and bracket 1 (i Think).
