Dimitri, Protective Prince

Royal Lineage — Whenever Dimitri attacks,
put a +1/+1 counter on it. If Dimitri attacked
this turn, you may counter the next spell to target it. This ability activates only once
per turn.

Crest of Blaiddyd - Roll a d6: If the result is 5
or greater, double +1/+1 counters on Dimitri
until end of turn.
