After the bacon we got the sugar :/
Nonplusultra instosis incoming.
Depending on implementation instosis may not be possible.
If the wording were tweaked to:
"Target creature can use its skill twice a turn for the next 3 turns. Afterward, it cannot use its skill the next 3 turns."
That would imply the effect would not start until next turn, preventing it from being used to circumvent the 1 round delay for skill use.
This would also help make it a little more distinct from SoR.
Even as is it is now, however, this card would expand the range of creatures instosis could be used. Players would still need to use SoR to make it work right since it does nothing to lower skill costs. This would mean increasing the number of cards required to make the combo work.
I do like the card, but I think skill use delay still needs to be respected to prevent abuse. Also 3 and 3 seems a bit much (6 turns total duration) since the average high end games only last about 8-10 rounds... 2 and 2 may be a little better. It also helps with balance a bit since delay effects would be a more effective counter.
By the way, will multiple uses stack? If so then it should definitely be reduced to 2 and 2.
