Upgrading some lands in gruul/rakdos colours to bring them up to speed with the other colours.
Added some hybrid persist cards over weaker guild options, though these enable some combos so are on probation. Added some more interesting guild cards, not necessarily signposting archetypes as I am trying to move away from rigid archetypes somewhat. Trimmed weak aggro cards that were baiting newer players, added some more scalable aggro threats that can be used in other decks.
Trimmed the simic spells matter section as it was very difficult to put together, added some more flexible pieces in their place. Upgraded some removal.
