Leveling up your Summoner Cards is important. When you Level up your Summoner, it allows you to Level up your Monster as well and that's very cool, because you have more of a chance to win in general, you can be more creative with your lineups, and it's just more fun overall! !-_-#!
See the Xenith Monk here. When he gets the heal, @ Level 2, he is a much different card. On a side note, I also, recommend his twin brother Tenyii Striker for the Fire team, at least in Bronze and Silver and lower mana battles.
Archery, often an overlooked skill in Splinterlands is also a very cool part of the lore. When one Watches & Listens to the Story and the Lore, one has a greater Understanding* of Betrayer* & Defenders*
Igor Darkspear has a lot of value here in Little League.(Only 2 Mana)
At Level 1 - 1 Archery Attack, 3 Speed, & 4 Health.
At Level 2 - 1 Archery Attack, 3 Speed, & 5 Health.
At Level 3 - 2 Archery Attack, 3 Speed, & 5 Health.
And At Level 3, Igor gets 2 Archery Attack. For Only a 2 Mana Card, that's value!
