If I understand correctly what is happening, the issue of redeeming other players' destroyed heroes is no longer raised, which means that the standard rules apply, allowing this procedure. And the ban during the tournament, we consider it a misunderstanding...
7. It is forbidden to: redeem your dismissed heroes on the same day (i.e., use the "dismissal-redemption" tactic);
it is also forbidden to buy heroes who died in battle (do not confuse with those who fled)!
And the fact that some participants, due to the previous discussion, understood this point in their own way is their problem. Moreover, VDV Forever clearly stated his position in post 116
Question: is it possible to buy a dead opponent's hero in this tournament?
no, it is not possible! A dead hero cannot be resurrected.
This statement was the last in the discussion and put a logical end to it.
