Notable Changes From Season 55

See below for last season's list:

The main change is testing Dominus Spark and shuffling around engine/non-engine so I had 14 starters / 19 handtraps in 45.

Dominus Spark was a pretty contradictory card. Originally, I thought I needed to change my main and extra deck to accommodate the restriction - adding lights / darks like Defenser. I found the restriction did not come into play as often as I expected for the following reasons:

1. You see Dominus Spark 30.3% of games in 45 cards (33.76% for 40 cards).
2. Half of those games are going 1st where the restriction does not apply.
3. While going 2nd, a fraction of those games are played in combination with Circular restriction where the LIGHT/DARK restriction is most problematic.
4. A fraction of the fraction of games, Spark needs to resolve to apply the restriction. Cards like Impulse, Caesar, Baronne were notable endboard pieces that negated Spark.

The decklist felt significantly worse when I made changes like Defenser and Singularity / Protectcode in the list to accommodate the Spark restriction. There were more games played without the restriction that it made no sense to keep these changes.

However, all I did was prove to myself that the restriction is not a big deal. Was the effect of Dominus spark impactful? I do not think so. Nibiru, Purulia, Sloth were all non-engine that performed better than Spark. It was nice to have Spark as a going 1st card for removal, but I kept thinking this card could have been Droplet or Crown or Ogre. To be more charitable to Spark, I think it had little chances to shine into my most common matchups like Crown Crew and Dracotail.

Matchup Breakdown in Total (175 Duels; 92 Heads, 83 Tails)

Due to Tenpai/Striker/Mikanko influence: 95 Going 1st, 80 Going 2nd

• 19 Clown Crew (10.9%, W/R = 52%)
• 14 Sky Striker (8.0%, W/R = 78%)
• 13 Dracotail (7.6%, W/R = 46%)
• 13 Elfnote (7.6%, W/R = 92%)
• 13 Kewl Tune (7.4%, W/R = 46%)

Honorable Mentions: 12 Tear, 10 Maliss & Mitsu, 9 Branded & RT Zoo

Clown Crew was a surprising addition to the ladder. This deck may be the driving force for not playing Spark in the future since it does so little while having to play through Purge, Harmonia, Ash. I might consider Belle and and Ogre instead.
