not at all. Thunderhorn in Vet can’t do anything the turn it’s played so you can hold something to deal with it. Lost might kill 1 back line value nerd but (similar to Makantor) shouldn’t be a game winner unless you play into it.
A “squad” mentality plays around both (as much as one can play around both) simultaneously. I’ll try to keep one or two guys with me and and have 2 more that stay together- but separate from myself and my “squad”. That way we are immune to a raw Lost and if Thunder comes out we already have a degree of space, giving us more breathing room/options.
as far as Gauntlet goes- I HATE draft formats so I just don’t play it at all.
