So I was derping around and saw this and realised that (perhaps pointless but...;p) noone posted stats about SoSer!! I was bored today and made a SoSebow and recorded the extra (non first entropy) cards that SoSer provides its owner.
So here are my results,
100 Shards of Serendipity casted, cards gained:
Quanta Producing: 35 cards - 17,5%
Spells: 67 - 33,5%
Creatures: 65 -32,5%
Permanents: 33 -16,5%
Cool and somehow interesting now,
Cards according to elements:
Entropy: 17 -8,5%
Life: 8 (!!) -4%
Air: 17 -8,5%
Water: 11(!) -5,5%
Aether: 16 -8%
Time: 18 -9%
Darkness: 16 -8%
Death: 17 -7,5%
Light:19 -8,5%
Fire: 17 -7,5%
Earth: 17 -7,5%
Gravity: 18 -8%
Other: 9 -4,5%
Most elements are equal to cards but dunno if coincidence but SoSer gave water and especially life less cards.
Just wanted to post those! If anyone cares about the deck used(vs AI4) here it is:
