Just running through my thoughts to make sure I'm playing correctly.
504. Draw Step
504.1. First, the active player draws a card. This turn-based action doesn't use the stack.
504.2. Second, any abilities that trigger at the beginning of the draw step and any other abilities that have triggered go on the stack.
504.3. Third, the active player gets priority. Players may cast spells and activate abilities.
614.6. If an event is replaced, it never happens. A modified event occurs instead, which may in turn
trigger abilities. Note that the modified event may contain instructions that can’t be carried out, in
which case the impossible instruction is simply ignored.
614.7. If a replacement effect would replace an event, but that event never happens, the replacement
effect simply doesn’t do anything.
I believe I can do what I want to do with these cards with the following game state:
- Chains is in play
- Moor is in hand
- Loam is in the yard
- I have a black mana available
Actions I need to take:
- Draw card for my turn.
- Cycle Moor.
- Replace one of these card draws with Loam's dredge.
- Move to my first main phase.
The expected resulting change in game state is:
- I drew a card from my library
- Loam is in hand
- Moor is in the yard
- I have one less black mana available
- I did not discard or mill to Chains
Is there something I am missing that it would cause it to not work like this?
