I know this is a special case, - since it only concerns RT, Fractal and I guess Mitosis - but the rewound creature's cost seems too high. The lowest costing dragon costs 10 and has stats of 10|5. So 10 for a 7|6 or 8|5 doesn't fit. 8 or 9 would be a better cost in my opinion.
And now to build a Rainbow Pandebow with this and Voodoos just for the fun of it!
The original rewound versions had 10 HP and a lower cost (8 and 7 IIRC), but people said it was too overpowered, so I lowered and raised them respectively. Maybe that was too much change at once? I could drop it down to 8 for both if you think that would work. Though the second idea behind raising the cost was to raise Eternity's value over RT in countering this creature: ie., reusable soft CC is better than splashing soft CC spells.
Good idea, still the ancient version has too many HP, 2|10 for 2 is too good by himself
The HP was that high to give Gravity a truly CC-resistant creature and (relatively) cheap creature. I hesitate to change anything more for the Ancient versions...do you recommend a specific change in cost or HP?
