A new player need some answers

By Magnot2, in Warhammer Invasion Rules Questions

Hi, i am a new player of Warhammer Invasion and i need som answers according cards. What does it mean when a unit has for example raider 2 or terror 2 information on it? Whne i build a deck - how many unit cards do i need and how many action cards? Is there any good piece of advice how many cards of each type do i need? is it possible to have a good deck without neutral cards? Thank You so much for help any players who find some time to answer my questions:)

Raider allows a unit to gain resources equal to its raider number if it survives combat.

Feared blanks the text box of a number of units eqaul to the Feared number while the Feared unit is atacking.
