220 TC in 2 fights without a Booster happens only when people bet on you and your opponent, and you win.
If I recall correctly, winner gets 1 % of all bets.
So, if there were these bets:
100, 100, 500, 200, 5 000, 1 300, 8 000.
100 * 0.01 + 100 * 0.01 + 500 * 0.01 + 200 * 0.01 + 5 000 * 0.01 + 1 300 * 0.01 + 8 000 * 0.01
= 1 + 1 + 5 + 2 + 50 + 13 + 80
= 152 TC

And other ways...
There are many, many ways.
a) By playing the game.
Normally win your matches
(10 TC in each official server, except in Ultimate servers, where you gain 15 TC each win)
Purchase a booster to get more TC each win
(Pay by
Mobile phone or
PayPal)
Game Events
(Tournaments, replay events etc...)
Betting
Dueling
(In fact, a really bad way, because you can be easily tricked and
you won't be paid...
I say avoid dueling.)
Bounty Hunting
(
Alternatively...)
b) By making art.
Design Events
Requests and shop
Projects
(On some projects, they seek artists to make some kind of art for them, e.g. icons or banners.)
c) By doing... Other stuff
Marketing
(Or
Items)
Random events
(They mostly are in
Game Events forum... Events like
the Great "500" Event or
Retro games comp. Pretty much random contests, you get the idea?)
Giving out GOOD ideas for Projects
d) Purchase dem!
(Well, you probably want to check the
Items section for a lot cheaper prices.)
