Hello, all. I've come here after looking for deck advice on the GoblinsMTG subreddit... I hate just jumping in the middle of a discussion, but I did want to ask one question as I am trying to build into the deck over time, starting mono-red with the core cards and add over time as budget allows. That being said, what would be a cost effective sideboard? The main themes I notice in sideboarding are (1) taxing effects for storm like Thorn of Amethyst, Thalia, Guardian of Thraben, and Sphere of Resistance. (2) graveyard hate like Grafdigger's Cage, Surgical Extraction, and Rest In Peace, and (3) artifact hate like Tuktuk Scrapper and Tin-Street Hooligan. Any advice for a starting point on building a sideboard for the Classic version with the more affordable options (like Grafdigger's Cage over Surgical Extraction)? I'd like to play the deck but can't shell out for 3 Chalice of the Voids on top of buying the main 60. If this wouldn't work, though, which would you prioritize at least? I feel like I at least need a taxing effect, GY hate, and maybe a coupleBlood Moon?
I'd love any and all advice getting into the deck, as it's been one of my favorites to watch videos on, etc. for years.
