True. You could replace a small minion with a larger one so your summons is less likely to pull poorly. e.g switch druid of the swarm (battlecry ignored from pull) with a greedy sprite (to boost mana off deathrattle) or an even larger taunt minion such as tar creeper.

However, you have a 50/50 chance to pull good targets anyway (Ironwood Golem, Astral Tiger and Crypt Lord), and if you mulligan and play minions such as raven and beetle early, summons has a much higher chance to pull a good target. Thx for the feedback.
