Elspeth, Storm Slayer

The static ability rewrites every one of this Elspeth's own outputs before it does anything else: the +1 that reads as a single Soldier writes two, and the doubler applies to any other token source you control as well. That reframes the whole card. A planeswalker's plus normally trades tempo for a slow board, but here it lands as a two-body play the turn she resolves, and the doubler compounds with every other token maker in the deck rather than sitting inert until an ultimate. The 0 is the payoff that closes on the doubled board: an anthem of +1/+1 counters plus flying turns a wide, cheap ground stall into lethal evasion in a single activation, and the counters stick after the flying wears off. The minus is the concession that keeps her defensible, an answer walled off from anything under mana value 3 so she cannot simply erase an aggressor's whole curve; she wants the board full of her own bodies, not trading one-for-one. What distinguishes this from earlier go-wide walkers is that the doubling lives in the passive, not in a single explosive activation, so it rewards a board that already exists and every token spell drawn afterward. The doubler is not a button you press; it is a tax on time she collects the moment she hits the battlefield.
