Critical Strike + Enchant transfusion

[Santar]

Hi mages!
My creature A has Critical strike and makes melee attack. Then I reveal Enchant tranfusion and my second creature B want to attack with this piersing 3 bonus. Question: will it works?

From suppliment:
If an effect grants an ability with a limited number of uses, then the source of that effect keeps track of the ability’s use.
Example: A Bloodcrag Minotaur is enchanted with Akiro’s Favor and uses the enchantment’s ability to reroll its attack dice. Its controller then casts Shift Enchantment to move Akiro’s Favor to aDwarf Kriegsbiel.TheDwarfKreigsbielwill not be able to make use of the ability on Akiro’s Favor this round because it has already been used by the Bloodcrag Minotaur.

So, I think no.

the answer is yes.

A'sF sais "once per round" (for the enchatment) -> no second time.
CS sais "the first melee attack this creyture makes" (for each creature) -> move it!
