クリーチャー — ゴブリン・ドルイド
1 / 4
あなたの終了ステップの開始時に、あなたがコントロールしているすべてのクリーチャーのパワーの合計が8以上である場合、カード1枚を引く。
Owlbear Shepherd's ability has an intervening if clause, which means that it checks to see if creatures you control have total power 8 or greater both as it would trigger and as it resolves. If enough creatures have been removed or their total power is reduced to below 8 by the time the ability tries to resolve, you will not draw a card.
