Tribute Summon

In order to Normal Summon a monster whose Level is 5 or higher, a monster(s) you control must be Tributed as a cost. Monsters that are Level 5 or 6 only require 1 Tribute. However monsters that are Level 7 or higher require 2 monsters to be Tributed. When you attempt to Summon a Level 5 or higher monster, you will be asked to select 1 or more monsters you control as a Tribute. The selected monsters are sent to the Graveyard, and the high Level monster is then Summoned to the field.
