Recursive Lulu (Lab Deck)

I really think people are sleeping on Lulu as a champion for this lab -- she's inexpensive, meaning not only can you play her early but her jailors only have 3 HP, plus she is pretty easy to level and can level off-board. Oh, and at L2 she can also Barrier your own usually-useless jailors on defensive rounds and turn them into 5/5s attacking into vulnerable units on offensive rounds. I've had a blast with this deck.

Like most support-based decks board control is paramount, so you're going to want to mulligan for some decent 1 or 2 drops and always keep an eye out for cheeky trade opportunities via cheap tricks like Pale Cascade / Rush / etc. Early in the game you'll usually prefer to open-attack as Lulu's buff is less impactful the more both sides develop, however the singleton nature means topdecks are less consistent so I find this is less true in the late game. This deck will give you a lot of options, so take your time deciding the optimal play.

Good luck!
