Madness at the Darkmoon Faire Cards List & Guide
Give your hero +2 Attack this turn. Add 'Second Slice' to your hand.
The slice so nice, it'll cut you twice.
Nerf this cancerous card to 1 mana
Pairs with Kael'thas Sunstrider, and helps control your hand for outcast. Could've been just a twinspell, but the artist made two images for it.
What's a twinspell? Blizzard forgets mechanics after the expansion is over. It really bothers me.
The thing is, it actually works diffently: twinspell gives you a copy of the card exactly in place of the one you played (same hand location), while the 'add' mechanic puts another card in the hand, meaning on the right, as you just drew it. This makes Twin Slice even better, because you can 'outcast' the second copy
Okay, you're actually right, I didn't notice that.
But there's also one more thing I didn't get the first time: Twinspells give you their copy even if they're cast without getting played. I'm pretty sure when Yogg casts a Twin Slice, you won't get a Second Slice.
I guess it does. It's one of the card effects: gain +1 attack AND add Second Slice to your hand
But I swear it doesn't...
