Whenever equipped creature attacks, tap target creature defending player controls and put a stun counter on it

While a 3/2 for four mana isnt great, the ability to counter a wide range of effects (spells, activated abilities and triggered abilities) or destroy a creature or planeswalker when Ertai enters makes this card an amazing Swiss Army knife that can answer a number of kill-on-sight threats, often in a surprising way, as the fact that this card counters triggered abilities can really stymy a foes game plan in unexpected ways
If a creature you control would enter the battlefield with a number of +1/+1 counters on it, it enters with that many plus one instead
