Sengir, the Dark Baron is nearly fully broken...

The adding counters part works fine, but the secondary effect half works, but does so incorrectly...

Whenever another player loses the game, you gain life equal to that player's life total as the turn began.

If a player dies, the turn it was summoned... It does nothing... Otherwise, it seems to add the life total the player was at when they died (not what they started the turn with)

Both happened in the same game (Local AI, just playing around)

{4}{B}{B} Legendary Creature — Vampire Noble 4/4 Flying Whenever another creature dies, put two +1/+1 counters on Sengir, the Dark Baron. Whenever another player loses the game, you gain life equal to that player's life total as the turn began. Partner (You can have two commanders if both have partner.)

Worked fine in my testing. In the examples, the player had 2 life at the beginning of the turn it lost the game.

Might be an AI issue since the game log shows that the AI had it under their control
