Neheb, 1TK Insult/Ribbons

Made this as a gift for a friend. Basic idea is to utilize the early game to build up an attack that will hit your opponent for 5 damage when you have Neheb, the Eternal on the field. Knowing that you can deal 5 damage to your opponent, you cast Injury from your hand before the combat phase, this spell doubles the damage done and damage cannot be prevented. Neheb gives you 10R mana (1 mana per damage done), you cast Ribbons from your graveyard as an aftermath spell using the 10R mana as it's Xmana cost. This forces each opponent to lose 1 life per 1 mana spent. You have now turned 5 damage into 20 life lost using Nehebs mana ability and 2 spells. Total life lost is 10 Total mana cost in 1 turn is 5 Total turn it takes to kill opponent is 1
