If he had used the tiger to deny the early mana tile/get cheap spells early on it would have been the correct play, but judging by his statement, this wasn’t the case
Also i am not saying it was the wrong play, i can’t tell since i haven’t seen the game. But if my opponent wins the game on 6 life i should always check twice if i really had no way to do 6 more damage during that game before i call some niche lategame card broken.
And yes, when you play against a deck with more lategame power then your own then the most vital ressource you have to account for is the enemy life total. This has nothing to do with “unkillable board generators” which Death Knell isn’t, this is simple strategy and Matchup knowledge.
