I define casher based on their attack and defense decks.

Light casher  - Attack or defense deck boosts to over 150k if they're using a full booster team, or if they have reducers with 14k in either attack or defense.

Cash player - FH and TR in scq and tower, limited rare summons, maybe a few good rare summon deamons like onimaru and yeti, perhaps one bell daemon from barter.

Whale - same as above, only with 3 or 5 mags on their cards.

Mega whale - Bell summons with max skill or deamons with skill with dramatically increase or decrease with max skill level.
