Aimor is a very specialized trap. It's speciality is best used for grinder deck. Like Jinteki PE and Weyland Builder of Nation. It can work well also for damage deck.
Why is it good? Because it trash 3 cards from the stack, no questions asked. Unless the runner as Engolo or an AI (usually Aumakua), they cannot interact with Aimor, making it an auto trigger. Trashing 3 cards from the stack mean 2 things. First, the loss of probable important cards is real (losing that Stargate or Liberated Account can really screw a game plan). Second, that is 3 less potential hitpoints to get City Work Project or Obotaka Protocol. If the game run long, the corp will win because the runner cannot score anything anymore.
Is it the best trap? No. Sadaka or Mganga would be better traps. But in specialized deck, it can really shine. For best effect, pairing Aimor with Preemptive Action and/or Genotyping allow you to bring it back (and any other traps).
Outside of grinder decks, you'll be better off with regular ices or other traps. One thing to add, what do they mean my Aimor? I seems to mean love in latin, but I do not see the link with the effect of the card or the flavor of the text.
Love in Latin is 'amor'. Considering the card is from the Down The White Nile set it seems more likely that 'aimor' is a word from a language in Africa. My google-fu fails me though, as near as I can tell it seems the likely origin language is Ateso. I found an old dictionary that has 'aimoromoro' as a word meaning abuse in Ateso, but I can find little else.
