add me SHaaBOii <| sep |> Long term use of that will give you peripheral neuropathy . Some people who do it once end up with constant stabbing pain in their fingers and toes <| sep |> This mechanic was my topdown design of emulating an MMO raid in MtG the idea of ' assists ' on kills , which encourages working with your opponents . Its a very loosely defined term that can ' t be quantified in black border , but the basic rule is that a player helped to destroy a creature if he or she took an action this turn that resulted in it getting destroyed . For example , lets say you ' re in a match against opponents A and B , and A controls a Raid Crusher . If both you and B teams up to kill it , and you both cast a Lightning Bolt on it , both of you helped kill it . But , if you cast Lightning Bolt on it , and then B casts Murder on it your Bolt didn ' t help at all , so you wouldn ' t get any counters . This doesn ' t just apply to damage though you can untap an opponent ' s creatures to let them block . You can Negate a combat trick that would have let it live . This will be a mechanic in my custom silverbordered set Unplugged . Creatures in white , black , and green will care about assisting in killing opponent ' s minions , while creatures in red , black , and green will be overcosted fatties with bounties on their heads .
