How it works
Proceed to your next cleanup step, causing you to discard cards down to your maximum hand size.
Containment Construct triggers for each card discarded this way. Resolve the first trigger, exiling the discarded card.
Ketramose triggers, causing you to draw a card and lose 1 life.
Shabraz triggers, causing you to gain 1 life and putting a +1/+1 counter on Shabraz.
Resolve all remaining Containment Construct abilities, if applicable, choosing not to exile anything.
Once the stack has emptied and all players pass priority, you will still be in the cleanup step and thus need to discard cards down to your maximum hand size.
