(10/4/2004) If there is more than one Propaganda on the battlefield, the cost is cumulative
Creatures like Arasta of the Endless Web, Ancient Greenwarden, Archon of Valor's Reach, Quasli Slingers, and Silklash Spider all work very well here
They are mainly useful for deterministic combo loops where the same prompts, priority passes, targets, mana choices, and stack-order decisions repeat several times
It also has decent synergy with manlands, which already dodge Whites exile based removal (except for March of Otherworldly Light), as placing two counters on an Inkmoth Nexus and attacking with it every turn leads to a surprisingly fast clock, especially with additional copies of either the land or Hardened Scales
If you control a single Lunarch Veteran, your Heliod, God of the Sun will enter the battlefield as an enchantment
Its great on turn 1 to find a two drop or mana dork, or an engine piece that synergizes with your Commander
