Emiel The Blessed is bugged, please help! :(

Hi!
First of all thanks for your great efforts with XMage, a fantastic resource for all Magic players....THANKS!
Then...I want to report a bug on the activated ability of **[Emiel the Blessed](https://scryfall.com/card/jmp/3/emiel-the-blessed)**. i.e.: "_{3}: Exile another target creature you control, then return it to the battlefield under its owner's control_".

I played a lot of local Commander test matches (free for all) against bots on localhost with my cEDH deck Sisay Weatherlight Captain. Having Emiel The Blessed onboard often it allows only one activation of its ability, while other times not even that, even if you have a large amount of mana available! The ability of Emiel can also be activated at any time when you have priority (and does not require tapping Emiel), however with XMage it seems possible to use it only in the main phase and only once (or never, as happened in some matches!). Once used it can no longer be used.

See below a log of one of the match: as you can see I was on my 1st Main Phase, I tutored Emiel with Sisay ability, I had a lot of mana but I couldn't activate Emiel's ability even once and I was forced to go ahead to next step!

_"10.10, T6.M1: wwwmagnottait searches their library (source: Sisay, Weatherlight Captain [924])
10.10, T6.M1: wwwmagnottait puts Emiel the Blessed [90d] from library onto the Battlefield (source: Sisay, Weatherlight Captain [924])
10.10, T6.M1: wwwmagnottait's library is shuffled (source: Sisay, Weatherlight Captain [924])
10.11, T6.DA: wwwmagnottait skip attack"_

This bug significantly weakens the Sisay's deck and all the other decks that use Emiel as a combo outlet.
Would you kindly check this issue and try to solve it?
Many many thanks!

No source file or test is named in the issue. Start by reproducing the Commander scenario from the match log with Emiel the Blessed and inspect the card implementation and activation handling; done means the ability can be activated whenever its controller has priority and sufficient mana, including multiple times.
