Mono-dark orthodox drain is classic and fun to play once in a while; if you spin Black Dragon, Devourer, or Dusk Shiled then you pretty much have to make a drainer.
No you don't. There's plenty of combinations of cards you can use.
I roll a random element that I have to incorporate into my decks. For an experiment I just rolled and got
. So, with that combo and one of the cards you mentioned, I'd probably go for something like Vampires, Adrenaline and Siphon Life. If it was the Devourer, then I might go for a drainer after all (after all, making the Oracle card an integral part of your deck is a good thing. It's for this reason that, for example, while I'll usually automatically give a thumbs down to a rainbow, I won't do so if the Oracle card was Supernova), so I'd probably go for something like Mitosis, Eclipse, Siphon Life and some
quanta so the Devourers could burrow. Maybe Siphon Life again.
Of course, I'd have to play the deck myself a few times to see how the AI plays it (I can see, for example, problems with the AI burrowing the Devourers and then just sitting on the Mitosises) and modify accordingly (or abandon entirely if it doesn't work), but that's part of the fun. Creating something, testing it, then leaving it to do its thing once you know that it'll do okay.
Of course, I don't expect everybody to play the game the way I do, and I recognise that my method is both more difficult and unorthodox. And I also agree that there's no harm in putting out a bog-standard deck every now and then - I've done it myself. In fact the deck I've got up at the moment isn't particularly clever (although I'll bet it's not what most people would have as first choice for a
deck - not one single Graboid). But when you can tell exactly what cards a deck is going to have in it just from the element of the Oracle card and the element of their Mark, then it's a sorry situation. So I just wanted to point out that the idea that if you draw a
card you
have to make a draining deck is wrong.
And if you do step outside the norm a little you can do well. I've been top 100 with a Vampire/Adrenaline deck before now. My current Graboidless deck is 4-0 after less than a day and sitting at 111, despite the fact that most people would have gone straight for Graboids (if they were locked in to doing a
deck, anyway). And you know what? If I draw an interesting card tomorrow, I'll probably make something new, even if my current deck has risen up the ranks and looks like a contender for the top 10. If I don't, I'll leave it up.
I just think that playing the game is more fun than winning it. That is supposed to be the point of games, right? To enjoy playing them.
