Hey all,here are some situations/cards i need to double check a few things on,thanks in advance for the replays

1: Ok so you have Trostani, Selesnya's Voice and Geist of Saint Traft on the battlefield...you attack with Geist of Saint Traft and you put the 4/4 angle onto the battlefield...two questions 1) would Trostani, Selesnya's Voice trigger ability go off and you would get 4 life or no because it says "put" and not "enter" ... 2) is "put" and "enter" the same effect?? I don't think it is,i just need to double check here.I hope i explain this right.

2: Say my opponent cast Bonfire of the Damned and he makes "x" 8 mana (say they cast it for the mirale cost) and in reponds i play Mystic Genesis The card reads at the end "where X is that spell's converted mana cost" The converted mana cost would be whatever the card comes onto play as...so in this case it would be 9 mana wouldn't it? and you would put a 9/9 Ooze onto the battlefield correct?

3:The card Nightveil Specter is say at the end "You may play cards exiled with Nightveil Specter" That means i can cast those cards at the appropriate time does it not? Creatures during my turn,Instants in reponds etc etc with paying there mana cost of course. Play and cast means the same thing does it not?

Thanks again everyone
