so i just throwed again but i learned and want to share. seemingly there is a logic at the end of the turn and effects trigger in row.
i knew this guy had played a trap with venus and tried to play my own trap to destroy it while positioning my phobie on the same hexfield.
my phobie taked damage and my trap also disappeared. so lost lost.
When traps are triggered, weather from another trap being placed on them, or another phobie, the trap detonates. If anything is in the effect range of the trap, they will take damage.
ah ok, its detonation. thank you for clearifying. in any case this ends as a lost - lost scenario, losing the health and the trap
