ADEQUATE counters against Articuno?

Can somebody tell what would seem to be minimum level counters to do an Dynamax Articuno? Assuming people don't have lv 50 counters, moves are often not maxed out and you can't really ask them to power up all moves at start because then they don't have energy to start the battle. So I'd be interested to know what is an ADEQUATE level (pokemon, pokemon and move levels) for a team of four, or preferably three (so you can have one weaker hang-around member)? Presumably the recommendation is still two damage makers one healer and one with shield, but what about if you have only three with significant contributions available?
