>>14738798Yeah, except his wording omitted the intervening if trigger for damage dealt. It's actually closer to:
Equipped creature gains Tap: If target opponent's hand contains 0 cards, you may have them lose 2 life. Otherwise, target opponent reveals their hand. You may activate this ability only if you and your opponent control a land with a portal counter.
This card is terribly designed and out of flavor: Doesn't it make more sense to be "Creatures you control are unblockable as long as both you and your opponent control a land with a portal counter on them" or something to that effect? It seems weird that it does not involve creature combat.
