Big update for the April 27th event!

These changes are ones that I've been wanting to make for a long time. My goals were thus when making these changes:

• Remove cards that are power outliers
• Remove cards that are don't have a home
• Add cards to make things a little more interesting

New themes:
This exists to give some more spice to things that either didn't really have a theme or replaced an older theme to give it more spice.

W Soldiers
W/B Clerics
W/U Flash
U/R Exile from Graveyard
R/G 4 Power Matters

Themes Strengthened:
These themes didn't do as well as I'd hoped. So I made them stronger and more cohesive.
G/B Graveyard
5 Color stuff
W/G Enchantments
Artifacts

Themes weakened:
These themes usually outperformed others and needed to be toned down a bit.
R/x Sneak Attack
R/x Control

Lands:
I've replaced some of the lower picked lands with the surveil lands and artifact lands. The artifact lands I chose because the artifact decks tend to need a critical amount and these help boost cards that needed help like nettlecyst. Surveil lands are plenty good.
