What I love about this sideboard is that the deck remains focused on its game plan even after the sideboard cards come in
When this deck attacks it is typically because it is going super wide
This deck is focused on using the enrage mechanic to provide you with numerous advantages, as well as quickly getting out enormous dinosaur creatures
For example, if X is 3 and you target a 2/2 creature, you will double its power once to 4, again to 8, and a third time to 16, making it a 16/2 creature until end of turn
Build a board of a cannon fodder, force your opponents creatures to the grave, draw cards, and transform Sephiroth to drain your opponents out
My only beef with The Capitoline Triad is most colorless Commander decks are running lots of Eldrazi as their top-end, and those are traditionally creatures with huge power and toughness already
