My environment is high powered (albeit not in a traditional way) and
Time Spiral, double
Frantic Search, etc, cause the mana doublers to typically shine in blue decks. But I think I can provide some good examples of how to use the doublers in purely Red/Green decks which can work in high and low power-level environments alike.
Let's start by looking at green land cards. Obviously Heartbeat decks scale with the number of lands you can amass. For example these cards are good in the lands deck, but also shine
on the heartbeat turn itself.
The same goes for anything that searches lands untapped:
Aside:
also gets you lands untapped.
The all-star lands win condition also works wonders w/ heartbeat:
Red serves as a way to make green heartbeat decks feel more "storm"-y. Red has a lot of card advantage cards that typically require you to invest more mana all at once, which fits perfectly with the mana doublers. Some examples:
Works wonders with oracle/mina. Then you can also throw in Top-of-Library manipulation which riptiders sometimes put in their RUG sections:
e.g.
The red card advantage suite which fits in the heartbeat/mana flare decks:
Reforge fits in the ToL manip theme too.
Aside: don't forget that red also has access to:
Red also gives X spells and
Pyromancer's Goggles for a possible win-con (although I hesitate to include literal
Fireball with this in my environment. I chose
ravaging blaze instead).
R/G incidentally has
which rounds out some good playables which aren't heartbeat specific. I really like that RG gives you the flexibility to go either the creature route or a noncreature route.
Win Conditions:
- x spells
- big creatures
- noncreature-specific payoffs
- spell velocity payoffs
Note: that you have to be really careful with heartbeat and mana flare. I think a lot of drafters will get trapped by them the first time around. It's extremely dangerous to just play one and then pass the turn (often your opponent will abuse it and then destroy your heartbeat). I typically like a way to get out from under the effect in emergencies e.g.
Reclamation Sage at the end of your big heartbeat turn. This is even easier in blue where you have:
which are all good in storm-style decks anyway (although upheaval is way higher power level).
