So I've been thinking about designing a cube with the twist that players play with this beautiful piece of cardboard in effect as an emblem. This has been one of the most fun cards in my Type 4 cube and we've even played casual constructed and cube games with it, it is just such a blast. Unfortunately, the mana cost is prohibits it from being an include in pretty much any cube. At this point I want to see if I can get a 360 list together that actually looks like something I want to build, but first I have a lot of questions to answer about how to actually put this cube together.
What are the implications of giving every creature haste? Fetchlands, top, etc, probably need to be excluded for power level reason but what about slow fetches, temples? How many I/S do I even want in this format given that they become inherently worse?
Vortex has a rules interaction where the card revealed on top does not enter, so ETB triggers don't occur. Static things like planeswalkers getting loyalty also don't happen. Should I even include ETB creatures? Are some worth running? Are planeswalkers worth running? Should planeswalkers work in this format and be able to use an ability on top of library? Is it worth bending the rules?
Let me know if I'm completely off my rocker here and this is a terrible idea.
