Brimstone Roundup

Whenever you cast your second spell each turn, create a 1/1 red Mercenary creature token with "T: Target creature you control gets +1/+0 until end of turn. Activate only as a sorcery." Plot 2R (You may pay 2R and exile this card from your hand. Cast it as a sorcery on a later turn without paying its mana cost. Plot only as a sorcery.)
