If Indominus Rex isn't on the battlefield as its last ability resolves, use the number of counters that were on it when it was last on the battlefield to determine how many cards to draw.
If Indominus Rex isn't on the battlefield as its last ability resolves, use the number of counters that were on it when it was last on the battlefield to determine how many cards to draw.
Indominus Rex's first ability will give it only one of each kind of counter, even if you discard more than one creature card with the relevant ability.
If you put counters on Indominus Rex before its last ability resolves, those counters will count.
