just saying this as a PSA if you have alot of free box 2/1 (the red and green ones from watching adds) they mostly contain common quality cards which includes engines (i4/v6/V8/i5) i have around 150 of them cuz i never really opened them but i opened 10 of the red boxes and got 2 v8s so if your need engines this is alot better than trying to get them from random boxes or srks imo
