When Beza enters, create a Treasure token if an opponent controls more lands than you. You gain 4 life if an opponent has more life than you. Create two 1/1 blue Fish creature tokens if an opponent controls more creatures than you. Draw a card if an opponent has more cards in hand than you.
Beza is a mono-white value engine that rewards being behind: cast her for a burst of resources (Treasure, life, Fish tokens, a card), then loop her with flicker and reanimation to repeatedly catch up and out-grind the table. The deck plays a midrange-to-control game, using her bodies and ramp to build a wide board or fuel go-wide payoffs while grinding incremental advantage.
Immediate, repeatable value when blinked or recast that helps mono-white's notorious card-draw and ramp problems
Flexible payoff that scales naturally against stronger opponents since the triggers check 'more than you'
Cheap four-mana body that's easy to protect and reuse
Slots into many white shells: blink, tokens, aristocrats, or lifegain
All four triggers are conditional, so when you're ahead Beza does almost nothing
Mono-white still struggles with raw card advantage and removal of problematic permanents
No evasion or inherent way to close the game by herself
Reliant on enablers (blink/recursion) to maximize her ceiling
