Legion Loyalist / Winota Joiner of Forces

So I was playing Winota Joiner of Forces and I attacked with Legion Loyalist and 3 goblin tokens which procs Legions (Battalion) which gives all creatures first strike, trample, and can’t be blocked by non tokens until end of turn. I search for my 4 humans because of Winota assuming they will get those affects because they’re creatures I control and it’s still my turn but everyone at my table was telling me that doesn’t work since they came after Legion was played. That doesn’t sound right to me can I get a little insight.
