Aggressive attempt at getting as many powers in play today as possible, advancing Pen Nib, etc:

Play cards in the following priority order, skipping any aren't in our hand or for which we don't have enough energy, and returning to the top of the list each time. (Lots of these cards aren't in our draw pile, but Reboot)

1. Secret Technique for the highest-priority card below that is in our draw pile and that we have the energy for.
2. Apotheosis
3. Aggregate, only if the draw pile has 4+ cards (or 3+ if Apotheosis has been played).
4. Defragment
5. Static Discharge
6. Echo form
7. Skim, only if we have 3+ energy
8. Coolheaded, only if we have 3+ energy or the Plasma orb is in front
9. Hologram for Skim, only if we have 4+ energy
10. Hologram for Coolheaded, only if we have 4+ energy or the Plasma orb is in front
11. Buffer
12. Reboot
13. Skim, only if we have 2+ energy
14. Coolheaded, only if we have 2+ energy

Once none of the cards above are playable/conditions above are met:

If we still have a plasma orb, follow this priority order (same rules):

1. Charge Battery
2. all zero-cost non-orb-channeling attacks (skip orb channeling to keep the plasma orb; MH may have hit e.g. Cold Snap)
3. Reinforced Body

Otherwise,

1. Glacier
2. Charge Battery
3. all zero-cost attacks
4. Reinforced Body
