Gr Tron Help Question

I have Gr tron due to my meta being largely aggro and wide creature based. (affinity, elves, merfolk, goblins, etc). Recently, a large influx of death's shadow has come into my meta, being at 4 seats in the top 8 consistently. Since I normally do well with the deck and get to top 8, I have to face these shadow decks along the way and consistently lose. What is this subreddits recommendation on what to do and how do I beat Death Shadow decks as Gr Tron? Thanks in advance.
