Holy Ward - Holy Glyph reworks could just use a mana cost. I'm really liking these, plus my version can help resist teleports.
EX: Holy Ward
holy 2 enchant target zone
cost: 2 reveal 4
Whenever an enemy non-mage creature makes a move action into this zone, it's controller must first pay one mana.
or
EX: Holy Ward 2
holy 2 enchant target zone
cost: 2 reveal 4
Whenever a non-living creature makes a move action into this zone, it's controller must first pay two mana.
and
EX: Holy Glyph
holy 1 enchant target zone or target enemy creature
cost 2 reveal 3
Same wording as [mwcard=MW1E22]Hellfire Trap[/mwcard] but instead an attack, holy glyph attaches to that creature. Whenever this creature would leave the zone, it's controller must first pay 3 mana. If this creature successfully leaves the zone, Holy Glyph attaches to the starting zone and flipped facedown.
PLUS
EX: Sanctuary
Holy 2 enchant target zone
cost: 2 reveal 4
Opponent's spells targeting this zone or a friendly creature in this zone must first play 2 mana.
