As an additional cost to cast red permanent spells, you may pay 2 life
There was a lot of work to get the game ready for its eventual launch
Just like The Lord of the Rings: Tales of Middle-earth, this means Wizards has no end of content to pull from
in cEDH, Blood Pet is often found in Krrik, Son of Yawgmoth builds as a way to net an extra mana for 2 life, but also sees a lot of play in Inalla, Archmage Ritualist and Ad Nauseam lines to rush out these expensive spells or aid in comboing off with other cards to win the game
For the Final Fantasy Secret Lair drops, however, it seems like Wizards may have learned its lesson
You will definitely need a scream container to hold the excited outbursts at the full product line-up for Attack of the Vine
