However, ask any professional player, and they will tell you that mastering small spell usage is the defining characteristic of a Grandmaster.

Small spells are the glue that holds a deck together; they provide unparalleled utility, fix rotation errors, and secure massive positive elixir trades.
The Small Spell Trinity
The Log is the king of pure ground control; it boasts the widest area of effect, pushes all ground units backward, and deals the most damage of the three.

The Zap is the ultimate utility spell; it hits both air and ground, deploys instantly with zero travel time, and crucially, resets the attack animation of any unit it hits.

You cast The Log immediately behind your Hog Rider; the Log rolls forward, crushing the skeletons the exact millisecond they spawn, securing a guaranteed tower connection.

Small spells also synergize perfectly with virtually every card in the game, turning near-misses into confirmed kills.
