Resourceful Defense

Counters are usually welded to the permanent that carries them: kill the creature and the +1/+1 counters vanish with it; sacrifice the planeswalker and the loyalty goes to the grave. This enchantment severs that link. When a countered permanent you control leaves the battlefield, the counters survive the trip and land somewhere else you control, and the activated ability lets you relocate any number of counters between your permanents whenever you can pay for it, including at instant speed on an opponent's turn or in response to their removal. The design answers a specific structural weakness of counter-matters decks: their value is fragile because it lives on bodies opponents can remove. Here the counters become portable, so a kill spell against your creature stops functioning as a reset button. Both lines read "counters" without qualification, so the effect is deliberately type-agnostic: +1/+1, loyalty, charge, oil, and whatever mechanic prints a counter next all move the same way. The mana cost on the activation is what keeps this from being a free every-turn shuffle, and the trigger only fires on permanents that already carried counters, so the card does nothing until you have counters worth protecting. That gives it two faces at once: insurance for a proliferate engine or a loyalty pile you would rather bank than lose, and combo glue for any deck that wants to accumulate counters in one place and cash them out somewhere the payoff lives.
