Since my polymorph meme has only garnered three downvotes so far I thought I'd offer a bit more controversial take, and see if I can manage to stir the pot a bit with this one.

As a DM I don't mind rules-lawyering, but you better be prepared for Consequences later on.
I am a big believer in the rule of cool and as long as everybody is having a good time, I don't mind looking the other way if a player makes a creative interpretation of the rules.
...But you better believe I'm gonna spend some time thinking about what should happen thematically if your wizard starts draining their own death energy to revive themselves.
I like a number of the suggestions here. I think my "solution" here would be to let once slide. The second time, I hand the player a folded note informing them that the toes on their left foot didn't come back with them, causing a visible limp, reduced movement speed and -1 to DEX.
...And we can build from there. Possibly start building a Final Destination style plan.
Cheating Death must have Consequences.
Suggestion: Lich Taint
They haven't become a lich by any means, but they've been touched by the aspect of lichdom. Lich's being rather territorial, they will be noticed by any others with associations to a lich, and that lich will be curious...the player will be investigated. If there is a reason for them to remain curious, expect an interview and serious questions.
