Onakke Oathkeeper

Planeswalker protection is usually incidental: you leave up a blocker, you race the ticks, you trust that opponents have better targets. This is the rare piece built to make attacking a superfriends board a taxed decision rather than a free one. The static ability doesn't forbid the attack; it prices it, charging one generic mana per creature swinging at your walkers, which turns a wide alpha strike into a mana problem the attacker has to solve before declaring attackers. The body backs the intent: a 0/4 that isn't trying to win a race, only to survive as a durable speed bump while the tax does the real work of keeping loyalty on the board. The graveyard ability turns the card proactive, and it also spends it: for six mana you exile it from the graveyard to return a dead planeswalker, trading the wall itself for the recursion. That trade is the point. The tax that guarded your first line is gone once you cash it in, so the second ability is less a further layer of defense than a conversion, spending a spent card to reload the plan it was protecting. Most planeswalker payoffs guard the ones you have; this one first taxes attackers off them, then, from the graveyard, gives back one you already lost. It is narrow by construction, a card that only makes sense when planeswalkers are the whole plan, but within that plan it does two jobs across two zones that rarely share a slot.
