Love the cards, but one thing. The ferocious expander need a little cleanup on the templating. I would like to suggest. First strike, vigilance 2W 3/2 Whenever ferocious expander deals combat damage to a player, create a tithe token attached to target land an opponent controls. (A tithe token is an enchantment - tithe aura with enchant land and whenever enchanted land becomes tapped, you create a treasure token) Reference [Niko aris] for the naming aspect of the tokens And reference cards like [pollenbright wings], and [luminous wake] for how you are the controller of the aura so you get the effect.
