VANGUARD
You have the Power of Precedence
At the start of the game place a token in front of your planets. Whenever another player challenges your system (after they load the cone but before pointing it at any base or moon) they must first challenge your vanguard token. You each play cards. If you win, they must return home and end their turn. If they win, they may proceed with their challenge. No tokens are lost as a result of the vanguard challenge. If after challenging the vanguard your opponent has no challenge cards his turn ends. No consolation is gained from a vanguard challenge.
