A 4/4 flyer that makes all opponents discard is a good start for 4cmc, but that flip activation is awful: 7 mana, sorcery speed, and your opponents can respond with instant speed removal

During your opponent's turn, if a face-up "Dual Avatar" monster(s) you control, except "Dual Avatar Feet - Kokoku", is destroyed by battle or card effect: You can Special Summon this card from your hand, then you can apply this effect

Pichu is classified as a 3-Diamonds card in the Wisdom of Sea and Sky set
