With Alien shocktrooper and Alien Mars out, I've twice tried to use this to summon gangi'el but it only lets me send shocktrooper to the grave and not Mars, what gives??
Gangi'el is not technically an alien monster like it's asking for and duel links won't let you take the 2000 points of damage (not finding a suitable monster)
"Send any number of cards..." doesn't specify you need to select from the field and Alien monster. You should be able to send any monster from your side of the field regardless of its type.
You can send any monster you control to the Graveyard, but their total Levels still have to equal the Level of an Alien in your Deck. (Which makes the burn effect baffling, since in most circumstances, it's impossible for it to trigger.)
