Anti-Mage vs Mars

How this matchup plays

Trying to land a combo as Mars against Anti-Mage is often a losing battle. The entire game plan for Mars relies on landing Spear of Mars to set up his damage, but Counterspell can block the stun and ruin the initiation. Even if Mars forgoes the spear, his dependency on mana for God's Rebuke and Arena of Blood makes him a prime target for Mana Burn. Anti-Mage can easily drain his mana pool, leaving Mars as a big melee creep. Furthermore, if Mars does manage to trap heroes in his Arena, Anti-Mage can simply Blink out.

This dynamic means Mars can struggle at all stages. During the lane, he needs mana to be a threat, a resource Anti-Mage is built to destroy. Later on, Mars wants to force teamfights with Arena of Blood, but Anti-Mage is usually happy splitting the map and avoiding those fights until he has key items. When he does join, he can stay on the edges, looking for an opportunity to blink on a spell-casting Mars, burn him dry, and finish his team with a huge Mana Void. Mars can't effectively initiate or control the one hero who dismantles him.
