1 - Searching the trade center I read the "TE" alot, figure it out it stand for "Time Elixir" (hope im not wrong) so, Where can I get them other than use mobacoins?
TE is the ingame currency, no confuise it with TE(p) as that is only for personal use and cannot be traded. TE is also used for certain events to skip the xx min CD of performing an action.
TE can be bought using coins or traded for with cards
2 - What can I do with extra artifacts? since they dont give another card for a new complete set
As far as i know, once u complete the set, they are of no use.
3- What`s kik?
a msging app ppl use ingame for communication or trades
