lv1 pw were matched with lv50+ in 3rd game in TG.

My opponents in 1st, 2nd & 3rd games were level under 11. then, I ran into lv55 in the 4th game.
how could the system match me with lv55 in late game?

new system?

I’ve seen this happen if it’s a relatively new Training Grounds event, especially if you’re in platinum. There simply may not have been enough registered decks to the event at a level appropriate to the planeswalker you’re using, and it continued looking up the levels till it found you a match.

it is happen with both plat and silver tiers, thare should been enought decks coz i played after event start for 10 hrs.
