Link to alias

Reason:

all of the card suits tags other than hearts (because it's <3) are pretty hard to tag, especially when your keyboard lacks a numpad. This is one of very few tags that you have to use an alt code to input (or copy paste it) and although it's not common it's kind of annoying when it pops up.

Diamonds_(symbol) -> ♦

<3< -> ♠

Spades_(symbol) -> ♠

Clubs_(symbol) -> ♣

a shortcut would be nice, but I think that *_(symbol) is a better alias for all of them, since it's very clear what they mean
