Skeleton Axolotl

Afflict 1
When this creature dies, instead place it into
exile as a 0/1 and remove all Axolotl counters.
At the beginning of your upkeep, if Skeleton
Axolotl is in exile, it gains an Axolotl counter.
Skeleton Axolotl may be cast from exile for {u/b}{u/b}+{x}, where {x} is the number of Axolotl
counters on Skeleton Axolotl.
If Skeleton Axolotl is casted from exile, put
X +1/+1 counters on it, where X is the number
of Axolotl Counters on Skeleton Axolotl.
