It would be impossible to not talk about Glacial Shift immediately after Ice Ram as both events are strongly connected. That is the big combo of Svara, but also, do not be afraid to use Glacial Shift on its own. In the right board state, Glacial Shift on its own can still provide great value. Shifting the board position, putting pressure on the opponent or just allowing your Ice Golems to all reach your opponent’s units, can more than justify this event in many cases.
Don’t misunderstand, you should still try to combo Glacial Shift with Ice Ram for really powerful turns, and probably around 50% of the time you will do exactly that. Just don’t be blind to the possibility of using it even outside of Ice Ram turns.
