Another 4 weeks passed by. Following is a list of tested/recommended Cards which were just not good enough. With time this list will be moved to the Description.
Please do NOT suggest the following cards. I don't play them for a reason.
Eternal Dragon - It's just too slow and mana heavy. If you don't take a mulligan when you have this card in your starting hand you are flat out stupid, if you draw into it on the first 7 turns you basically just lost a turn. If its in your graveyard and you "reanimate" it it costs 12 mana to have a 5/5 flyer. With 12 mana I could hard cast Avacyn, Angel of Hope and still have mana for counterbackup (8 mana for avacyn + 3 mana for Lapse of Certainty). Its actually better to play a basic land in this slot.
Leonin Abunas - Yes, it does protect my Equipment from spot removal. So does my Commander. And my Commander can still protect himself.
Argentum Armor - Again, too slow and too mana heavy. Yes, i could cheat it into play with a Stoneforge Mystic and Equip for 0 when i also have my Puresteel Paladin out with metal craft active. But 90% of the time that isn't the case. Basically what i am trying to say is, stop suggesting me Equipment that costs an amount of mana equal or near to the casting cost of Emrakul, the Aeons Torn
Champion's Helm - this actually is a good equipment for a Voltron Deck. Sadly I don't play a pure Voltron Deck. There are a bunch of Creatures in there, for example Mirran Crusader, that aren't legendary. In addition to that I could play a sword in that slot and spend 1 mana more and suddenly have an equipment that draws me cards and shoots stuff with the same P/T boost.
Darksteel Plate - Yay indestructible. For 5 mana. The things you could do for 5 mana...
Fireshrieker - There is no need for that Equipment. I've got 3 Doublestrike dudes and a Silverblade Paladin.
Loxodon Warhammer - This is not a budget deck. Batterskull is just better. It can bounce itself and it can beat people up without equipping it to some dude.
Sword of Vengeance - 6 mana for +2/+0? No thanks, this is not a budget deck.
Trading Post - It was in there at some point, but i don't really like it in that deck anymore.
Terminus - I don't want to mess up my own board. I have enough recursion to get things back from my graveyard, but digging them up from beneath my library? Not really worth it.
Oblation - Yes it can catch anything but letting people draw 2 cards at the cost of 3 mana is just not reasonable in a mono-white deck.
Mikokoro, Center of the Sea - >EACH< player draws a card. Each being the word we should focus on. My opponents draw cards too. Why should i fuel the Control decks around me?
Thespian's Stage/Vesuva - Yes copying utility lands is great but it does not really have a target in my deck. A possible target sure is Emeria, the Sky Ruin but if it is destroyed i still can get it back with Crucible of Worlds
All is Dust - Yes it does Purge the board and spares my Equipment. 8.5 can also turn lands and artifacts white so that they are hit by it. but 7 mana is just too much to pay, if you calculate in that you need 8.5 and 1 mana per permanent thats not white to turn it white and actually get rid of it.
Angelic Field Marshal - Heliod, God of the Sun might be better if i would play it for the mass vigilance, if i would play it just to have a flying dude, i rely too much on my commander to be out there and give the angel a P/T boost.
Citadel Siege - After some intense card reading it turns out that it says "..., put two +1/+1 counters on >target< creature you control". Most of the time i have got only 1 creature out there on the battlefield and that creature has got swords equipped to it which grant the creature protection from white, so i can't target that creature. And paying 4 mana for an Enchantment that does absolutely nothing is not really my playstyle.
Debt of Loyalty - According to the Oracle text, you only get the creature if it regenerates from Debt of Loyalty's effect.
Nykthos, Shrine to Nyx - Acutally not really good in a somewhat colorless deck.
Leonin Shikari - Is just good in combination with Puresteel Paladin + Metalcraft. Otherwise it's just a 2/2.
----There will be more additions to that list in due time.
