I was playing Arena Powered Cube

My side of the board was :
- Lands (not relevant)
- Pyrogoyf (3/4 at the time)

Opponent's side was :
- Lands (not relevant)
- Esika's Chariot
- A pair of 2/2 cat tokens created by Chariot

On his 1st main phase, my opponent crewed Esika's Chariot with both cats, turning it into a creature
At the beginning of combat, I flashed in Ertai, Resurrected. I chose his seconde ability : "Destroy another creature or planeswalker. Its controller draws a card." and was unable to target Esika's Chariot (bug). After trying, I had to settle for destroying a car instead, which made me lose the game quickly after and crushed my event run.
