the strike main board and form side board

Hi guys! Not sure if you're still following this, but I just got the in the mail deck today! I sleeved it and it's all ready to go. I am going to a modern event this Thursday. The person at the store I am going to told me it is rather competitive and I might see some tier 1 decks playing but the decks vary a lot each time, so I'm not sure what to expect. Suggestions for sideboarding and strategy against popular modern decks would be much appreciated! Thanks again for sticking with me!

How about Relic of Progenitus?

Sorry, still a bit of a noobie. That's for delve, right? Or a different graveyard deck? What would I take out in sideboard?

Affinity, infect, tron, living end, abzan, merfolk, podless pod are all common tier 1 decks.

Relic of Progenitus helps against storm, delve and reanimate decks. Grafdigger's Cage also helps against storm decks and podless pod. Counterspells help against living end decks. For affinity Hurkyl's Recall For tron matches Ghost Quarter. Choke for merfolk decks. For burn decks use Wild Defiance and Spellskite and I knoe some of these cards are pricey. But mainly for the sideboard it gonna take sometime of u going there and seeing which decks commonly popping up.

Gitaxian Probe was banned, so maybe add 2 more Slip Through Space and a couple copies of Might of Old Krosa?
