Timmy crossed with Uber-Johnny. I've a pretty limited collection, so I try to think of original uses for my cards in order to keep myself from getting bored. If I make a good deck, I usually take it apart again within a month.

I've often thought about this, but I could never really decide what category I fell into.

I usually start off by thinking I'm a Johnny. I'm an engineer by day, so I love to understand how everything works; I like to explore all the subtle interactions between cards and come up with devastating combos that others would probably overlook. When evaluating new cards, my first thoughts is, "How can I break this?", not so much in the sense of winning, but more to just use the card for unintended purposes.

I also enjoy tinkering with my decks, tweaking them until they're really good and can win very consistently, which I guess gives me a Spike streak.

Lately, I've been playing a lot more (during lunch with some friends at work), and I've gotten more into the social aspect of the game. I try not to play my really powerful decks very often, often retiring them after I've tweaked them to the point where no one wants to play against them anymore, which I suppose is a Timmy thing to do.

So, I guess my answer is that I'm a little of all 3 types...but I still fancy myself a Johnny.

I wanted to add something:

Spike is a 'netdeck-player' most of the times. People who recently started playing Magic, and need to get a good deck to get started. Money is not an issue. Google is your friend.

Johnny is also a 'rogue-deck' player. In formats where one or two decks are very popular (Jund for example), Johnny tends to play something completely different, like some weird non-combo deck. These decks are called rogue because they're mostly the sole deck of it's type in a tournament.

As for myself, I'm a pure Johnny.

I'm definitely Johnny with a bit of Spike. I also connect with Vorthos and Melvin - one of the reasons I disliked M10 edition is its total lack of plot.

This was also reflected in the card mechanics - the mechanics often are interrelated with the plot (e.g. in Alara the very existence of five different worlds was felt very strongly in the cards, flavor text, etc...).

Completely Jhonny and a litle bit of Timmy haha

Almost full Timmy. I love the experience of throwing creatures around, and the feel of spell-casting. If nothing else was enough to convince me, the fact that Rise of the Eldrazi was my first ever tournament pushes it over the edge.

I'm a bit Spike enough to enjoy a good play, but not so much that I feel good about sacrificing my creatures. Not even Eldrazi Spawn. Nor do I net-deck at all, or even trade much. I might go Johnny if I had enough cards, but it sounds like too much work.

On the other axis, I swing widely between Vorthos and Melvin. I enjoy the mechanics of game design, but I also enjoy the flavor of worlds. I appreciate both [[[Form of the Dragon]]] and [[[River's Grasp]]], but for very different reasons. "Exile" excited me both for its concise template and its perfect flavor. I've read several of the novels, as well as most of Making Magic. While actually playing, the two vie for dominance, usually depending on how much I need to concentrate on correct decisions.
