These Trap Monsters either have an effect that Special Summons them from the Graveyard as a monster (in which case they can be either a Normal Trap or Continuous Trap), or have an effect that Special Summons them upon their card activation (in which case they are always a Normal Trap)
Because the one-shot effect that returns the cards isn't an ability that goes on the stack, it won't cease to exist along with the leaving player's spells and abilities on the stack
Are there any good indicators/easy to spot stuff, preferably noticable even in photos I should pay attention to
Any recommendations
For example, if you've spent three mana on spells so far this turn and you control a permanent with an ability that triggers "whenever you expend 4," that ability will trigger the next time you spend at least one mana to cast a spell this turn
