tornado or ice

Hey iron core here. I need an opinion about two cards. The first card is koaki tornado its effect is to place 1 core on the top of your deck to destroy all special summon monsters your opponent controls. Then there's koaki ice which effect is to discard a card to destroy 1 special summon monster and you can do this as much times as you want. In this meta which do you think is the best. links below

Well, Meta being targeted won't help you at all, because some meta just can't be targeted, your best bet would be tornado, at least in my opinion.

Ice doesn't target... I'd prob run max destruction so tornado.

LGM, it does, OCG rulings bro

We're not using ocg rulings. Most tourneys are done with the tcg rulings .-.
