Daghatar the Adamant

The body that enters with nothing of its own and four counters bolted on is the structural trick here: print a 0/0, hand it a fixed pile of +1/+1 counters, and the creature is a 4/4 with vigilance whose stats live entirely in a movable resource. That distinction is what the activated ability cashes in. Rather than growing the team, it relocates: a counter peeled off one creature and slapped onto another, at a hybrid Abzan cost that lets the deck pay with whatever it has. The applications are all about repositioning power across the board, shifting a counter off a creature about to die to bank the value, stacking a single threat past a blocker, or feeding outlets that care about counters arriving. It rewards a shell already running counters as a currency, since the ability does not generate them, only moves what is on the table. The Abzan keyword identity of the era leaned hard on counters as a cross-card economy, and this is the piece that turns that economy liquid: a permanent that treats every +1/+1 counter in play as fungible, repayable mana on a stick. The vigilance is the quiet glue, keeping a four-power body attacking and still home to defend or to receive a relocated counter the following turn.
