Forum:Malevolent Mech Goku En Vs Macro Cosmos

Ok I have a but of an odd question to ask here.

Recently my friend and I were playing a couple of rounds on a program called Ygo Pro. Its sort of a hybrid of YVD and Dueling Networks, but I digress. I'm sitting there using my zombie world deck and he using I can only guess was a macro cosmos deck, when something odd happened. Two things, actually...

The turn before he activated macro cosmos. At the time, I had zombie world on the field and a spirit reaper. I tried to normal summon Malevolent Mech Goku En from the hand without tribute, but for some reason the program wouldn't let me, and I can't figure out why. I was forced to tribute my spirit reaper for Goku En.

My friend told me that it was probably because of the fact that Goku En coudldn't be sent to the graveyard, but I don't know if that's the case or not. A similar thing happened earlier in the duel. I had an endless decay and a spirit reaper on the field, and I was trying to summon red-eyes zombie dragon and instead of only using 1 tribute, it forced me to tribute both of my monsters, and I can't figure out why.

Is it some sort of ruling that I'm some how missing or faulty programming? Berserkfhurer (talk • contribs) 07:08, December 25, 2012 (UTC)
