There are card games that involve more than four suits, or more than one 
pack. In principle, if you draw ten cards from an unknown number of 
packs, you could draw ten Aces, or even ten Aces of the same suit. Think 
of playing blackjack with ten packs shuffled together.

Cripple Mr Onion, for example, uses hands of ten cards drawn from eight 
suits:

(yes, it's a real game, based on a fictional game)


The Indian Ganjifa deck uses ten "houses" (decks) of 12 cards each.

Pinochle uses the standard four Western suits, but uses two copies of 
each card 9, 10, J, Q, K, A, for 48 cards in total. Sometimes people 
combine two pinochle decks for larger games, so with a double deck all 
ten cards could be Aces.

In the 1930s, there was a fad for playing Bridge with a fifth suit, 
coloured green, called Royals, Leaves, Eagles or Rooks depending on the 
manufacturer.

There are five- and six-suit versions of poker, with at least two still 
commercially available: the five-suit Stardeck pack (which adds Stars), 
and the six-suit Empire deck (which adds red Crowns and black Anchors).

There is an eight-suit Euchre pack that adds red Moons, black Stars, red 
four-leaf Clovers and black Tears to the standard deck.
