After a lot of tweaking and some testing I decided that the right thing to do was to narrow down my sideboard cards making them fewer but stronger versus what I found problematic games 2 and 3
So, in order to prevent this creature from bringing destruction to the world, Papalymo sacrificed himself to cast the same spell his master, Louisoix, used to trap Bahamut at the end of Final Fantasy 14 1.0
The other big con is the cost of the mana base
That's because Vivi has an extremely powerful mana-making ability that almost feels designed for Savor the Moment
While it offers incremental value with its ability to boost other creatures on entering the battlefield or dying, there are likely better cards available in those color combinations that offer more impactful effects for a similar mana cost, like [[Conclave Mentor]] or [[Basri's Lieutenant]]
Bouncing permanents, tapping down a board before attackers, or even countering a spell all on top of drawing a card is just so good
