No problem, Omnath stores it for you
These tips come from my experiences, from what Ive learned going from playing Limited for years to a format thats wildly different
Black mana adds some removal and life drain effect to the deck, and Gilt-Leaf Winnower is a semi-evasive 4/3 that can kill a non-Elf when it enters the battlefield if it doesn't have "square stats" (same power and toughness)
The overall appearance remains acceptable: the card is clearly used or has defects, but is still in generally good condition
As for Dismember, it's a budget substitute for Path to Exile in the paper world (which is weird, because Path to Exile is actually significantly cheaper on Magic Online , so if you are building on Magic Online , you might as well play Path to Exile)
Double strike and trample is brutal enough, but then you take into consideration that it can be cast for as cheap as and attaches itself immediately to one of those unblocked attacking creatures
