Slip in a 5-color land for access to infinite colored mana and use that combat phase wisely
Furystoke Giant Furystoke Giant can be very powerful in decks looking to cast or create a lot of creatures
You may either change those targets to be legal in reference to you, or, if those are the spell's only targets, the spell doesn't resolve for having illegal targets
The next grouping could have more gems since theyre less obvious outside of EDH the way a lot of the top EDH cards arent given how good they are in other formats
Then it exiles when it leaves the battlefield, even if it would be tucked to your library or bounced to your hand, so this is a one trick pony
While the card is mainly for the control matchup, the -2 ability is particularly intriguing to me in its ability to allow Knight of the Reliquary to find a hatebear to protect it as wellbe it Gaddock Teeg , Sylvan Safekeeper , or even just a plain Standard Bearer
