What did I just play against

Been playing about a month now and I'm kinda getting my footing playing a dragonmaid deck that is F2p. I win maybe 1 out of 5 duels but that's alright I'm learning. I just played a deck I think it's called Runick? They just made me draw my cards turn by turn until I ran out and I lost. They didn't attack me once and I couldn't get anything setup without them stopping me. What the heck is this and why would anyone find that fun
