Opponent attacks with Drover Grizzly. After I declare block with my 2/2 mercenary token (+1/+1 counter) the opponent casts Clear Shot, buffing the Grizzly to 5/3 and targeting my mercenary. In response I cast Snakeskin Veil on the mercenary, canceling Clear Shot's damage and buffing the mercenary to 3/3. Damage resolves, the mercenary dies and the Grizzly lives with only 2 damage taken, whereas both should have died. Happened in OTJ quick draft on PC.
