It doesn’t, but if your opponent either missed their one drop or doesn’t have a decent two drop, you’re going to get at least two card draws off of the now 1/5 cleric, and can usually build up a nice board off of her.
This game is actually pretty easy to pick up in constructed. Arena is kind of difficult to learn at first, but once you get a grasp on what cards are must-picks, just alright, and complete ass (no matter what, don’t draft Wisps or Hungry Crabs), it’s quite fun, provided you aren’t playing against the lucky sack of shit that drafted 4 Perdition Blades for early game,and a Ragnaros for late game.
Shit is bad. Even though it is free, it’s a 1/1, and it’s a card from your hand. Spend the mana and get a one drop that will actually do something, or spend two mana and get something that’s quite good.
Hungry Crab is especially bad for being a epic. I know, you’ll feel like a bawse when the crab kills a murloc, but that shit’s rarely going to happen, since there’s only one murloc that will ever get drafted (the 2 cost 2/1 charger). Constructed, just use that card slot for a board clear, since that is what you’ll really need to beat murloc rush decks.
Perdition’s Blade is godlike. The combo effect will normally kill something outright when played as a combo (used as the second or later card in a turn), and it’s got good stats on its own. Being a weapon, it goes very well with the pirate cards that benefit from weapons being in play.
Ragnaros is a monster. Even if silenced, you can then swing his 8/8 body into things.
