The "mainboard" is the deck in its current state.
Maybeboard are cards that I am strongly considering or currently acquiring.
Holy crap. I love this deck. You gain control of cards, Sac them with card:Ashnod's Altar, Gain enormous amounts of mana. Well done. I am just confused on Braid of Fire . Do you have to spend the mana on the upkeep/lose it or does it carry over into the main phase. Either way is fine. Turn creatures with Olivia Voldaren at the upkeep, then gain control of them. Also, you should change your commander into her and not Spiny Starfish .
Braid of fire is for pinging for free during your upkeep. Indeed, I made this deck before the site registered olivia :) changing now.
