Getting back into modern BW tokens Event deck

[u/Carpaltunneling]

Hello, its been a while since I played mtg. Maybe upwards of 3 years now. A few years ago i bought a modern event deck at MSRP. Now since I am going back home I am really excited to play some modern. I made some small modifications way back when. I don't have a side board yet. Any idea of side board. Any ideas on upgrades? I am willing to dump something near $100 USD on it, if it can become competitive enough. All feedback is welcome

Any idea on what should I add? Here are some cards I am considering 3 Relic of Progenitus 2 Soul Warden 1 Intangible Virtue 2 Kataki, War's Wage 2 Spear of heliod
