Fire deck   while another mainly focuses

on grinding opponent's card all down to grave

including forbidding banning perhaps of graveyard

cards. while delaying incoming attacks, and existing

creatures or cretins on field via similar banning and time

decay moves.  cards sent to graveyard may form an

counter for certain future cards' effects in that way
