abandoned sarcophagus doesn't work properly...
Abandoned Sarcophagus exiles cards when you cycle them, instead of letting them go to the yard. It specifically says they go to the yard if cycled.
confirmed in game 718616020 match 246339869
if you cycle a card with abandoned sarcophacus on the battlefield it will exile the cycled card instead of letting it go to the graveyard.
it should be letting them go to the graveyard when cycled.
couldnt test further, it was destroyed.
