Normally I don't use the all out attack melee lineup.
However this time I saw no other option left because my rival had way better summoners than I did.
With this lineup I am able to increase the melee attack of all my cards by 2
My Lineup
To Start with my all out attack lineup my first card is the Goblin Mech. It has one of the highest attacks out there and it is also very good defensively
For my second position I decided to use the Manticore. Its reach ability makes it one of the best suited for it.
The Armorsmith occupies my third position. Its ability to repair makes it very valuable. I could have used another card with the opportunity ability though
Cave Slug: For an all out melee lineup the Opportunity ability is one of the best out there. The Cave Slug has one of the highest attacks
Silvershield Assasin: For rulesets with a high mana cap the Silvershield is amazing. Sneak and double strike are an amazing combo
Silvershield Knight: The most important part of my All out Attack lineup. It has the inspire ability which increases the melee attack of all my units by 1.
The attack of Manticore was doubled on this setup, something that proved very helpful.
I narrowly won the battle. Luckily for me my rival didn't have any card with the sneak ability.
