Wirewood sybiote removing creature from blocking would not allow trample damage to go through. I am not sure if this was because i played whirling strike on my picnic ruiner(with miiran bainesplitter attached) after blocks were declared but it should not of mattered. My assumptions is that the trample damage should of 100% gone to the player since while it was blocked that creature was removed. So all of its damage should of hit the player for lethal but the player took zero damage
