I was just thinking of an idea like this, but it would refresh all timers (except poison/neurotoxin/purify) and abilities of your creatures and permanents.
Time
Refresh 9
/ Refresh 8
Spell
Refreshes all timers and activations on creatures and permanents you control. Consumes all
.
(Sundial, Phase shield, Wings, Cloak have their timers reset to full. Creatures, permanents and weapons can use their ability again if they have already used it this turn). Now that I think about it, resetting timers could be overpowered in some situations. Albeit an an 8 card and tri-element combo, you could prolong one protected Phase shield to lasting 21 turns. With 5 other shields that's potentially 36 turns of phase. Either way this is neither here nor there.
I think the cost is a bit low for the effect. I think it's a very versatile card and can be splashed into many decks. In some cases I think it's actually more useful than Sky blitz for dived creatures and it might allow you to bypass summoning sickness (1-turn evolving Graboids?), depending on how it works.
I'd think increasing the cost to around 5
/ 4
might be better. Like you said you do have to pay the cost of the ability again, so it doesn't warrant a very high cost. At 2/1 Supernovas (or even Novas) pay for them all which makes it a bit too easy to play.
