The scope is far too large
And the value of cards varies with the mages playing (cost-benefit), other cards in the book and your local meta
For example, AlexW, you posted Pushy Wizard hence Eagleclaw up there
Yet in my meta, Veteran's Belt + High Armour has nerfed Thorns Push and Wall Bash
Interesting though this discussion will be, it falls prey to the same assumptions fas723 made with "most efficient creatures"
The reality is you would need to map out a Kohonen Network of card interactions
Then apply it to a changing meta propensity to encounter opponent cards to evlaute this
For example, in a meta of Buffed Forcemasters, Curse Stacking and Buffed Elites, Purge Magic immediately becomes a valuable threat.
There are just so many dimensions that I think the thread's subject should be de-scoped to just one aspect
Broadly your 5 categories are:
(A) Always Golden (e.g. Teleport)
(B) Toolbox Golden (e.g. Purge Magic) - reacting to opponent's strategy
(C) Workhorse - the majority - just don't talk about these and cloud the issue
(D) Niche Strategy (e.g. Rajan's Fury) - useful only for certain own strategies
(E) Waste of Trees (e.g. Destroy Magic)
I think the most fun to be had is a thread dedicated to Category (E) = laminate as a coaster
And then others can defend why those crads deserve to be in Category (D) = niche strategy
For example, if they release cheap mobile Demons, Gate to Hell is borderline Niche Strategy
But spending 4+SPs on reactive opponent's build-reliant spell like full action Destroy Magic is never going to happen
Another example: you hate Stumble
But actually it's Niche suitable for at least these strategies
Teleport to Monster Pit + Transfusion Jinx Nullify Force Hold Stumble
(Could be played in-school with Forcemaster Force Pull into Teleport Trap into Pit of 4 Psyloks if only better)
It could also help Warlord Ranged Strategy against Melee Units (e.g. 6 Falcons + 4 Rajan's Fury BM Swarm)
Aniother edge case: playing against Golem Warlord with a Helm of Charge
The problem is the mandatory reveal which I so hate in this game
We have this awesome mechanic where we bank actions as enchantments with instant speed surprise reveals
And then they nerf the most enchanting aspect of the game with dumb down mandatory reveal
In the case of Stumble, there is only a tiny window before it has to be revealed
What is the point of an enchantment you can't bank for surprise reveal as moving is such a common action?
To add insult to injury, Force Hold is non-mandatory, provokes Dispel for cost 3 and only costs 1 more mana
So Stumble becomes an incredibly situational "poor man's Force Hold" for those who can't afford 4SPs
I think they put it in DvN because thematically it fits with Horror Movies etc (theme plays a very high priority)
When really they are never going to catch-up on their promo card backlog so might as well forget failures
You've got me ranting again!
But mandatory reveal so annoys me because its a great game needlessly shooting itself in the foot again.
Just imagine what a high skill finesse spell Stumble could have been if it was not a mandatory reveal...?
