I've been playing MtG since 99 (yeah, Urza block is the best way to break into a game, lol).
On and off I played with friends and attended tournaments, participated in pro tour qualifiers and such, nothing really came of it though aside from a 1st place winnings at local tournaments (drafts and the occasional FNM event). But ever since my local store closed I haven't been attending any FNM events and such. Which is a shame, since I still have a fully functioning Soul sisters build for Modern sitting in a deckbox

However, I play Magic: online pretty much daily and somewhat competitive. I prefer Legacy and Modern over Standard (price is among the reasons why I prefer eternal formats of the "flavor of the week" format). I can enjoy Commander and Pauper from time to time and I'm quite a bit of a rogue deckbuilder I guess (not to be confused with the actual youtubechannel Rogue deckbuilder)
I have a fascination for combodecks (which means Legacy is the right place for me, right?) though I often pilot straight up mono-red Burn decks as well. Or Goblins. But I do most colors fine I guess; Death and taxes is such a fun deck. Oh and let's not even start on Dredge, it's playing a different game alltogether.
My favorite color, and thus favorite cards are all red. Perhaps add a bit of blue in it for shenanigans; I'm probably more Izzet aligned in that regard. Favorite cards of mine by far; Warp world, Grip of Chaos, Confusion in the ranks... and I guess honorable mentions go out to Mind's Desire and Eye of the storm.
Oh dear, I remember Urza is when I first started collecting the cards..so much nostalgia. Went to the same place that sold model jets for my model fix to get cards. I always liked black but all the colors in MTG have really cool stuff, even white. Always been a fan of the art so I collected them but never had people to play with.
