This card is insane imo. This is a wonderful mana sink for late game. Plus cards like fury will synergise well with it. However it's the rare type of cards you don't want more than 2 in your deck. Because one on the board is enough.
Might be interesting for OE as well with all the reduc cd, the ramp, and summons.
A good alternative to Waking Stones, will definitively bury Obelisk imo.
While Waking stones is more resilient against E, while Wings Shield (Winged Shield sounds better imho) is better against G/O. And might become insane with Plate Armor.
It's weak against E because of the nukes but also the AOE. It's better against G/O because you can stack your units behind and hit them more. But also because it's a human so you can move it, it can attacks so you can buff it with vanguard etc.
No seriously. This card can only be fun to troll your opponent with a binding roots etc. But that's far too costy.
This card might be the core of a future deadlock deck with ether pumps coils mortar etc. Because if protected an idol will take at least 2 for destroying it via a spell, or force your opponent to no play a single spell, for each of them on the board.
Seriously this card is a win win. It's either top priority to destroy it, thus protecting other precious things or it will cheap away your opponent life or force him to not play spells until it is destroyed.
This card has insane possibilities. It gives even more control over your opponent creatures to order, combo with all the order movement spell, and make use of healing spells such as Imp Ress, or may be resonant helm (this card is still terrible though).
Good, nothing more, nothing less.
It doesn't have any flaw and reward you for taking care of your creatures.
My 2cents on those cards.
