Finally found motivation to tune the list.

• Added a reach support package in G after finding lots of fliers getting through. UR/WUR still seems powerful. Added Arasta to directly counter this deck after playtesting with @endblink.
• Ditching full 'adventures' theme in WU. Focusing more on blink effects.
• BR had a bigger focus on equipment & knights, but the NEO equipment creatures inspired me. I will return to this colour pair when I need to. Focus is still on attacking with menace, equipment is a bonus. Embercleave is now costed 4RB.
• Other minor oracle changes include Consider > Surveil 1
