You're probably aware, but I'd just be careful putting Whispersilk Cloak on Griffin Canyon and not being able to use its ability on itself. Really cool deck. Love the idea of just messing with people. Haha. +1

Haha. Thanks! I'm glad you liked it!

Anyway, regarding Whispersilk Cloak, I'd use it when I'm in a pinch and not as an integral part of the combo. The standard evasion procedure is to use Wings of Velis Vel, View from Above, Shadow Rift, Artful Dodge, or Thassa, God of the Sea.

Whispersilk Cloak is useful in cases where spot removal is rampant in the game and you already got a large enough land you can use for the beats. I prefer to use it on a land where it's more than 21/21 already.

Jank as they come! Love it!

Just a few suggestions as I muddle through your long path to the griffony goodness of your manland win:

Mirror Entity is another card you can use to get the creature type. You can even pay 0 for the ability if you don't mind wiping your non-manland creatures in a pinch.

Ring of Three Wishes and Tamiyo's Journal are somewhat slow colorless tutors, but they're totally budget and get you to that oh so needed card.

Turnabout is good both offensively and defensively and creates you a manland.

Sacred Ground is similar to Terra Eternal in the fact it protects your lands from creature boardwipes of others. Yes they come back unmanned, but lacking strong GY recursion for them will make this deck difficult.

Ghirapur Orrery is a group-hug card that may benefit you most. Extra land per turn helps you gain presence and the draw 3 ability helps you recover gas when you've run out of your cheap cards.

Finally, consider Windfall and/or Jace's Archivist. If we're avoiding tutoring, you'll need as many ways to hunt for that land as possible.

Happy Janking! Hope that helps.

Thanks! I'm glad you like the jankiness that this deck brings!

These are good card suggestions and I might as well give out my thoughts on them...

1. Ring of Three Wishes/Tamiyo's Journal - while tutoring is good, these tutors might just be a little bit too slow and expensive to work on. At 5 mana, I might just be doing something to make an Island/Plains larger other than tutoring. Journal on the other hand is something that cannot be very useful at all in the incorrect shell. Trail of Evidence makes it worthwhile but that's another card I would need just to support a specific card.
2. Sacred Ground - I did have this in the deck a while back but there are just very few instances that its effect activates. For starters, it doesn't protect lands against Blasphemous Act and the like. It cannot even protect your lands during combat. The card is just too narrow to warrant inclusion.
3. Mirror Entity - used to be in the deck as well, together with Amoeboid Changeling and Imagecrafter. The reason I removed these changeling cards is that they are creatures and are easy to remove. Another reason would be because most of the time when Griffin Canyon is not online, they are dead cards at best. Infinite mana combos go well with Mirror Entity though. Hint: Altar of Dementia
4. Turnabout/Windfall - both are very good inclusions and would benefit the deck no doubt. The problem is that I don't know which ones to replace for these. Maybe replace Mystic Speculation with Windfall? Turnabout is bonkers under specific circumstances, especially when you have both Sapphire Medallion and View from Above. Grow a land very large in a single turn. Doesn't even need to be the Griffin Canyon.
5. Ghirapur Orrery - seems like a good card to help us ramp and stuff. However, we rarely find our self with an empty hand so the second effect seems moot.

All in all, here are the cards I'm looking to add from these suggestions:

1. Windfall
2. Turnabout

Great suggestions overall! Keep them coming!

Hi! I don't to talk much about your deck because I think it is as good as it is now but if you talk real jankyness you should run Darksteel Garrison! :D Equip any land to make it a Darksteel Citadel. Mostly to slow but it is on noones radar and is worth a laugh to run it but at the end a indestructible Inkmoth Nexus is no fun for everyone else! ;)

Hello! Darksteel Garrison is indeed a very nice card. Aside from making the one land that matters in the deck indestructible, it makes the Griffin Canyon combo more potent. It allows the Griffin land to buff all other creatures (just by doing its thing which involves tapping it) in my battlefield for a 1-hit KO across the table.

Unfortunately, Inkmoth Nexus is a card I'm on the fence on. Sure it allows you to win games easily, but where's the fun in that? Although for more competitive metas, nexus takes the cake as best lands in the deck.
