Cost evaluation needed for http://elementscommunity.org/forum/index.php/topic,33754.0/topicseen.html
The upped image and text disagree about the stats. I used the table.
Master of Ice has 2 primary usages that tend not to overlap. I will evaluate them separately.
Master of Ice is a Allied only version of Arctic Squid when used to Freeze your creatures for Catapulting. Arctic Squid is not balanced with this usage in mind and is not used for this purpose because it is UP in this usage compared to using multiple Freezes. Therefore to be balanced Master of Ice must be better than Arctic Squid at this usage and still not overshoot Freeze.
Master of Ice costs 4+X
+1 card for X freezes. (atk ignored because the freezing rocks win condition ignores such low attacks)
Arctic Squid costs 3+2X
+1 card for X freezes. (atk ignored because the freezing rocks win condition ignores such low attacks)
For an expected X>1 Master of Ice fulfills the first requirement.
Freeze costs X
+X cards for X freezes.
For an expected X<6 Master of Ice fulfills the second requirement.
Launches required usually fall in this 2-5 range.
A cost of 3-5
would be balanced here.
Master of Ice can also be used as a faster version of Vulture. (Water freezes
much faster than Death kills)
Master of Ice costs 4
|4
+ 1 card has 0|2 attack, minor hp and increases +1|+1 per creature frozen (Ice Shield likely)
Vulture costs 3
|3
+ 1 card has 0|1 attack, minor hp and increases +1|+1 per death trigger (Cat or CC likely)
Using Ice Shield, Master of Ice increases by +X|+X where X starts at roughly 30% of the opposing offense and slowly shrinks to 17.7%.
Since Master of Ice does increase faster than Vulture it should cost more than Vulture. I would estimate that a 5
|4
+ 1 card casting cost with 0 attack would be balanced with Vulture. If Vulture is OP/UP then adjust this estimate as you would adjust Vulture.
Sidenote: Master of Ice can be used as AntiCC.
