Alex, Prideful Conqueror

Alex can't be countered.

Converge — Alex enters with a +1/+1 counter on it
for each color of mana spent to cast it.

When Alex enters, draw a card for each +1/+1 counter on it.

As long as there are five or more +1/+1 counters on Alex, it has flying, first strike, vigilance, trample, lifelink, and indestructible.
