Token doublers used to be a static enchantment problem: Doubling Season, Parallel Lives, and Anointed Procession all sit in a fixed slot doing their multiplication, none of them threatening anything on their own. Folding that same replacement effect onto a body changes the risk profile entirely. The doubling now rides a creature that can attack and block, which makes it worth killing, and Ward is the tax that makes killing it awkward: an opponent has to answer a 2/2 and pay a premium for the privilege, or leave the multiplier online for another turn. Like its enchantment predecessors, the effect is deliberately broad, catching anything that reads "create": Treasure, Blood, Clue, Food, copies of your own permanents, all of it. Note the boundary, though: it doubles tokens, not counters, so it multiplies what enters as a token but does nothing for proliferate or +1/+1 counter engines that Doubling Season also touches. The color pairing is the tell for what this was built to enable. Green and blue is the home of both go-wide token strategies and copy effects, so a doubler there is not just a value piece but a combo axis, turning a single token-making trigger into a snowball. Because the effect is a static replacement rather than an enter-the-battlefield ability, it does nothing the moment it resolves; its value is entirely deferred to the next time a token would be made, which is precisely why the Ward tax matters: it buys the card the turn it needs to start paying off.
