The guy was full of leech cards. Valewarden would help.
You got Watchtower early so you had a card you couldn't play for ages.
Devouring Blades are disaster 😨
It's pity you didn't post the deck. People can comment your deck and, even their advice is wrong, you can re-think things and find better solutions. It often happens to me.
I have added the creature "Valewarden Minotaur" to my deck and also to "Simple Satyr", to heal my god.
"Devouring Blades" is a relic that I will add to my war deck, too.👍👍👍
