Imagine we have no more 2 cards of each suit. This means that we have no more than 2*4 = 8 cards at all.
Therefore, by selecting the 9th card, by the pigeon principle(9 cards and 4 suits), we will guarantee at least 3 cards of the same suit will be chosen.
Along with that, this number can't be less than 9, since we have provided with the example for 8 cards.
So, the least answer is 9.
