here is the deck
Warning! Terrible English after this line!
When I play in arena ,there is always a problem that short of upped card and Rekted so hard.
The only way to beat them is simply stop them from play any card,doing mana/resource control.
A good mana-control creature is Devourer | Pest, which provide u mana just as the
lands pillars at the same time,but 6 is usually not enough ,for in advanced area, just like gold and platnum, the AI will have a mark will 3 mana and 6-7 pillars , when it comes to rainbow decks it got worse for a single pillar of them will produce 6 mana in the first round and a supernova will end your dream of control mana using only 6 0/2 creature.
Also, mono-dark decks have problems with their spare mana, unlike other colors which have weapon/creature skills to get benefit from plenty of mana, the only creature can make some use of dark mana source is Black Nymph|Dark Nymph, which is neally hard to obtain,especially for new players like me, also, their ablity provide you life-link but also turn the creature into a fuse bomb,that is not the skill we want in this deck.
So I find mitosis in life, which can copy tons of devourer just for 5 life(4 when upgraded), unfortunately it is weak to removals for its copy can not do further copies, only the target can copy itself. I thought about use Fractal instead which is safer for u keep copies in hand,and u can play them at once, but that cost 9 aether which will be a great problem, also u need to empty your hand to use this, but u can't waste drain life(the only creature removal in this deck) and steal(best permanent solution,only weird facing flooding) for you may get punished for not keeping this 2, and in most of times u can only do 4/5 copies which is not enough for completely control the all folloing mana source and works as a Plan B Kill with nightfall|eclipse , vampires are also target of this spell for i haven't place any shield in this deck----most time you steal them, when you don't have proper shield, the life-link of vampires are only way u can survive until the time devourers get complete control, or win the race of death.
You will find 2 vampires are the only upped card in this deck for the unupped ones works too slow, can't get you out of danger, also unlike the upper ones, the small ones the still in the range of rain of fire even with nightfall, which is unacceptable. beside these, i recommend you upgrade the weapon when you get some moneys, for 2 dark 6 attack with life-link is very sweet. Also, the eclipse will speed up your winning and get more life from the vampires, besides these, you will not need any upper cards to win the sweet gift in arena, pay 20 as ticket, and get 200, some time even with upped cards or Shards!
I still find this deck is not perfect, and I will change it as soon as I find better way to make it more effective. These are the problem of this deck:
1. the 2 dragons , they are the fake targets of removals in AI's hand. they are strong enough to take 2 removals, which will be very useful.Also, when they copy themselves.
you will find you simply can't lose in a race. But if i have 4 vampires, will i replace them with vampires. or keep them for they have 6 defence under night fall?
2. the mana base, I play the game for only 2 days, I have really no ideas how to set my mana base, pends are not dual-lands, u can't choose it to produce a certain mana in the specific time. which make mana base seems really unreliable in this deck.
3. the vampires, is it possible to replace them with heal,Empathic Bond, or some other choices?
4. is it really better to choose life, not aether?
I am happy to see your advice/infomation on this deck, or one my poooooooor English, which needs to be upped before any card in this deck.
