If this card is Normal Summoned: Place 1 Spell Counter on it (max. 1). This card gains 300 ATK for each Spell Counter on it. You can remove 1 Spell Counter from this card, then target 1 Spell/Trap Card on the field; destroy that target.
Target 1 face-up card on the field that you can place a Spell Counter on; place 1 Spell Counter on that target, then you can add 1 "Spell Power Grasp" from your Deck to your hand. You can only activate 1 "Spell Power Grasp" per turn.
I play this deck with dark valkyria and it's really working out for me.
I'd actually recommend Chow Len the Prophet over Kycoo. That way, you have multiple sources disabling the opponent's back row.
If you call it right, you can either force the opponent to use their card early, or lose the ability to use said card for the rest of the turn. Even if you call the card wrong, you now know exactly what their face-down card happens to be, and can now plan around it.
Magical Something might also help, since both Enemy Controller and Offerings to the Doomed are quick-play.
