OK so for clarification on some issues:
As to stacking well unless you are really lucky you would be unlikely to have more than 1 of these cards in your deck and being God cards you can only have one in play at any one time.
This is an extremely important piece of information when it comes to evaluating your card idea is not mentioned at all in the opening topic post.
When it comes to posting mass numbers of ideas have no issue. It is mass numbers of Untested ideas. Without notes or details of what you were trying to do it was just a post of an overpowered mono-type anubis.
I did run some calculations and decided that as a monotype creature I could run a sprinting Time deck and now also have immortal 16 attack dragons. Even with a one per deck (OPD) i had it on the table and could run buffed dragons straight up rather than having to wait till the endgame condition. In Rainbow I was able to replace 4 quints with the reusable and buffing Ra. Otyugh, Ra'd for a 3|8 Immortal Devourer, Fallen Druid 6|6 Improve making it more resistant to fire buckler. I could even increase my time tower ratio to increase the opening speed of the deck at a smaller more efficient size. I could find no reason why I wouldn't use this card as it is more powerful than anything else currently printed and makes several other current key cards redundant.
My Momentus Vampire of Buffness deck was extremely fun and very easy to run thanks to Ra. Dropping an 8|5 Momentum Vampire Immortal every 5 turns was fun.
I have no wish to stifle your creative effort ScytherLol so try not to take offence to what I have said, but your ideas are unmeasured and uncalculated but presented as being worthy of a final result. If everyone follows this trend the Card Ideas area will simply become cluttered with damaged ideas and the effort for Zanzarino or anyone in the future to garner a useful submission will be so high that they will all be ignored.
