As you can imagine, being a Stage 2 Pokmon (meaning it needs to evolve twice) that requires 4 energy to set off an attack 1 Water, 1 Lightning, and 2 colourless you need to buy yourself some time
This lowers the Speed stats of those hit
So if you have 10 creatures on your board, you can pay just to put in your hand 7 of your cards and if they happen to be instants or sorceries, Witherbloom will discount them too, of course
P.S.: I wanted to include Songcrafter MageSongcrafter Mage either as winner or runner-up, but it only grants harmonize to another card and doesn't have it itself, so it was not eligible
Damage : The number next to the attacks name shows how much damage the attack deals to the opponents Pokmon
This card is a great option for going second in a duel
