If you have any engine that triggers whenever a card leaves the graveyard (Insidious Roots), or a prowess card, Lluwen can power that up, while it makes sacrifice fodder for more death triggers
The card Triskaidekaphobia which causes players on exactly 13 life to lose the game is already confirmed for an Innistrad Remastered reprint, and it would be a real shame if its blue mana counterpart were passed over
Yeah, it has a ton of power
Having the ability to consistently draw upwards of 3+ cards per turn will put you on the track to win the game
Its the set that introduced the block cycle, and the first set explicitly designed with Limited in mind
The usability of this card is insane given that it can easily be an Energy Card engine for your other Fire-type Attackers and can come in clutch given that it only requires 2 Fire Energies to attack with a 180+ damage output
