Ban: Yes / No
Also, what does 'Ban' mean in cube context? Surely you mean, 'remove from my cube'?
I'm in favour of keeping it, too. I think my main problem with it is the 7 Wonders problem. Like, you draft and play optimally for your seat, but based on the decisions of other players across the table from you, someone else is able to assemble the unstoppable killing machine, and steamroll everyone in their path. In that case, other than by random hate-drafting, there isn't really much you can do to control your own fate, and your inevitable loss comes at the hands of the other randos who supposedly didn't do their jobs cacking key pieces of the combo.
Is it really people's fault for letting Restoration Angel pass them by, though? Who was even in white that could've used it? Jonas was essentially one-drop aggro, and Dom was all-in on the aggro lifegain theme.
CML, is there any way your G/U deck could've interacted with a five mana 2/2? I forgot what was in your list, but can your deck win three games of ten in that matchup? Even if Jason jams all the red and white removal in the world, I'm not sure what some colour combinations are supposed to do about this.
not much it's U/G it doesn't interact. I had a Venser and a board Rift
i love kiki-jiki
2/2 for too strong
