In Hearthstone, one of my characters is an ice mage. I have two Cryomancers in the deck (+2/+2 if minion is frozen) plus 2 Glacial Shards, so there is considerable synergy between these cards. I frequently face the problem shown below: should I use a Glacial Shard on Turn 1 as an opener or save it for later synergy?
In the screenshot above, you can see I opted to use it in turn one. The freeze effect is wasted, but on the plus side, I have a minion out on turn 1, which puts pressure on my opponent. By using it now however, if one of my Cryomancers is drawn I will have no immediate way to get a +2/+2.
