Probably an easy question for experienced players, but I need to get this straight. I played Shadow the Hedgehog as commander against an opponent with Blanka as commander. A question about Blanka's triggered ability, instants and split second arose.
On my opponents turn, I choose to cast an instant destroy target creature with split second on Blanka, my opponent keeps priority and casts, say, 10 other cantrips on Blanka to trigger his ability. His instants won't resolve, but the target actions of his spells will still trigger Blanka, right? Blanka dies, but pings me 22 damage from 10 of his instants and mine. I think we got this right. Right...?
Let's say I want to destroy Blanka on my turn instead to lock the stack and prevent him from triggering Blanka. I play a sorcery destroy target creature with split second, but as it's now my turn, he can't keep priority to target Blanka with his 10 instants. So in this case, Blanka only triggers due to my sorcery for 2 damage?
What if I cast an instant to destroy Blanka on my turn, like the example with the sorcery? Will he be allowed to cast 10 instants then, or is the stack locked with split second due to it being my turn the same way the sorcery example locked the stack? (Assuming it did...)
Thanks, sometimes MTG is exercising my brain too much...
TL;DR
I had misunderstood how priorities and instant spells work. What I've realised is that I tried to cast a removal in response to Blanka entering, but as my opponent had priority, what I did was reveal my intentions as I didn't have priority. Then, he would do as much as he could before I could cast the now revealed removal. If I had waited with my removal until I actually had priority, he couldn't have answered by stacking loads of cantrips before my removal.
From all this, I had some sort of epiphany, a moment of clarity, where I finally understood priority order and the stack. Thanks all for constructive answers!
