@Team 7: what to post next for Ezuri?
Waking up in a medical room, pain, poison, antidote, outchies.

About the training collabs, we can't post them anymore but you can consider those skills (tactical thinking) learned over the duration of the chuunin exams. Let's say he learned them before, but only realized how to put them into practice a bit better after the exams. Valuable life experiences etc.
