Frootloops
By far our most cursed and unpopular gimmick, Frootloops was devised by OzzieOCE, one of the SEQ TOs. It has two aspects, first is deck building, where instead of not being allowed multiples of the same part, you aren't allowed parts with the same colour. The second is scoring, which changes the points scored for each finish type, and introduces scoring 5 points for 3 wins in a row, which in the group stage would be an instant win.
Gimmick Rules
Deck Building
Build a deck of 3 beys with no repeating colours. Repeating parts are allowed as long as they aren't the same colour.
Painted parts are considered the original colour of the part.
Colour Categories
To keep things simple, colours are grouped into the following categories. You may only have one part from each category in your deck.
Red
Orange
Yellow
Purple
Blue
Green
Pink
Brown
Teal
Black
Grey
White
Part Colours Considered
Many parts have multiple colours, as such only one of the colours are considered for the no repeating colours rule. For each part these are:
Blade - Inner plastic colour (the colour on the bottom of the blade)
Ratchet - Outer section colour
Bit - Bottom section colour
Assist blades and lock chips aren't counted.
Matches
Spin finishes are 0 points
Over finishes are 1 point
Xtreme finishes are 1 point
Burst finishes are 2 points
Winning 3 battles in a row scores you a "Sugar Rush", scoring you 5 points
Spin finishes count toward a Sugar Rush.
Group stage matches are First to 5. However, points scored over 5 are counted, as they affect seeding in the finals bracket. For example, if you get 3 over finishes in a row, your score is recorded as 8 (1+1+1+5).
The finals are a gauntlet style bracket with seeding determined by points scored. Finals matches are first to 9 points.
My thoughts
This gimmick was quite unpopular with a lot of players, due to the unnecessary combination of multiple gimmicks, the vagueness of the colour rule, and since spin finishes are 0 points, you can often have periods of no progress in a match.
However personally I found the gimmick quite enjoyable, not so much the deck building aspect, which while it was a fun restriction it didn't add much competitively. But the way the match type shifted your focus and goals towards scoring chains of wins, or trying to disrupt your opponent's chain before they could take the match, was something I found to be fresh and interesting. It turned what is normally an inevitable march towards the end of the match into a back and forth, similar to the feeling of exchanging points at a deuce in Wii Sports tennis.
